Cuckold explained
Cuckold is a non-monogamous consensual sex practice, which has gained a lot of notoriety in the last decade, and has stood out among other non-monogamous sexual practices. With more and more adherents, especially among young people, the practice has drawn the attention of the scientific community to study the biological and psychological mechanisms behind this behavioral trend.
What is cuckold?
Cuckold is the term used for the sexual practice in which a man feels pleasure in sharing his spouse (wife, fiancee or girlfriend) with another man, who curiously, in the vast majority of cases is a black man. When analyzing adult social networks, dating sites, swing communities and the major amateur porn video sites, it is clear that over the last decade, there has been an exponential increase in cuckold supporters, making the theme increasingly addressed in conventional media such as blogs, newspapers, youtubers. With the increasing relevance of cuckold in society, biologists and psychologists have gone deeper into the subject to understand why this practice has stood out among other sexual practices in society today, and why the “white couple and black man” pattern is systematically repeated among practitioners. Studies indicate that the tendency to practice cuckold is related to biological, psychological and evolutionary mechanisms.
Cuckold: Response Mechanism to Sperm Competition and the Risk of Infidelity
Male sexual fantasies and competition between men
In a study published in 2002, Pound found that contrary to popular belief, men strongly prefer FMM fantasies, involving two men and one woman, over FFM fantasies, involving two women and one man.
Pound (2002) analyzed pornographic images on internet sites and showed that depictions of sexual activity involving one woman and several men are more prevalent than those involving one man and several women.
Similar results were found in an online preference survey in a study that discreetly examined image selection behavior. McKibbin, Pham, and Shackelford (2013) reported that the number of images on adult DVD covers depicting multiple men having interactions with a woman ranks higher on DVD sales than having multiple women interacting with a single man.
Excitement in
response to competition and sperm.
A study published in 1993 by Baker, RR and Bellis indicated that males tend to increase ejaculation volume and sperm quality when their partner is at risk of being inseminated by another male, due to the effect of biological competition for fertilization. female. Evidence suggests that men experience increased arousal in response to the sight of their partner sexually interacting with other men (Talese, 1981; Gould, 1999).
Consistent with this hypothesis, (Kilgallon and Simmons 2005) reported that men who view pornography depicting two men interacting with one woman (high sperm competition) ejaculate a much higher percentage of motile sperm than men who view pornography depicting three women (absence of suggestion of sperm competition).
Thus, although men should avoid sexual situations with a risk of sperm competition, they may actually prefer the arousal associated with sperm competition.
The conclusion is that, intuitively the practice of cuckold explores the sexual arousal provoked by the biological mechanism of male reaction against the competition of sperm from another man. Although contraceptive methods prevent fertilization, the reaction mechanism provokes arousal by the presence of another male interacting with the female.
Cuckold or Cuckold Interracial? Because cuckold is strictly linked to racial issues.
According to the
study (Adrienne D. Davis, 2019), 83.6% of non-monogamous consensual sex (CNM)
practitioners are white people (caucasoids). The results indicate that couples
who engage in non-monogamous consensual sex have higher levels of sexual
satisfaction and higher sexual frequency than monogamous couples. The constant
pattern of white couple and black man indicates that there is some biological
mechanism that pushes cuckold practitioners towards this combination. The
answer may be related to the reproductive strategies caused by different
environments. Basically, reproductive strategies are defined as r and K
strategies:
Species adapted to the strategy-r:
They live in hostile
environments with few resources, therefore, produce a high number of offspring,
because despite the chances of survival are few, with a numerous offspring, it
is likely that some offspring will survive. Males tend to focus on high numbers
of copulations with different females, causing high competition between males.
More common in hot climates.
Species adapted to
strategy-k:
They live in
environments with more resources, less hostile and less risky, and therefore
produce fewer offspring, as there is a great chance that the offspring will
reach adulthood. Males invest more time in caring for their offspring and
female, so there is little interest in mating with other females and little
competition between males. More common in cold climates.
Exploring Sperm Competition: Is One Competitor Better Than Another?
Blacks are sexually more adapted to a high competition between males (Edward M. Miller, 1994), having a larger penis, which allows not only to inject sperm closer to the uterus (Short 1980, 1981) and (Halliday 1980), but also to remove sperm from another competitor, through the shape of the more developed glans (Gordon G. Gallup Jr. et All 2013).
Studies indicate that
Negroids have a larger testicular volume than other races (Jared M. Diamond,
1986). This volume is consistent with strategy r, since the larger testis is
needed to fertilize multiple females in a competitive environment. The most
developed testicular volume is observed from birth, as observed when comparing
the testicular volume of 1.14 ml black infants (UN Chikani, et all 2016) and
0.25 ml white infants (EAM Kuijper, 2008), where it can be verified that
Negroids are born with a testis 4.5 times larger than Caucasoids.
The testicle is of great importance in the early stages of life, influencing the development of male characteristics, penis size, bone muscle mass. In adulthood, the size of the testes is proportional to the production of testosterone and sperm, in addition to being indicators of fertility (Rosita Condorelli, et all 2013), indicating that larger testes indicate higher fertility rates, while smaller testes are related to conditions. of low infertility.
The study by (John Komlos, 2007) concluded that black children develop faster than white children of the same age. This difference in growth reflects a better adaptation of Negroids to more hostile environments than Caucasoids.
According to (Sabine Rohrmann et all, 2007), black men have higher levels of free sex steroids in their bloodstream than other races. Higher concentrations of extraditol and testosterone (J Natl Cancer 1986) are related to more active and dominant sexual behavior (Asian J. Androl, 2016). This behavior reflects the r strategy, in which it is necessary to have a high frequency of sexual activity to copulate with several females, while maintaining a dominant and aggressive behavior to deal with other competing males (Rushton, 2013).
The greater
resistance to diseases of Negroids was indicated by research such as (Hélène
Quach et all, 2016), that African populations have a greater immune response
than European populations, having resistance to malaria and infections (Michael
C. Campbell, 2010).
Because black men
have all the genetic, physical, and sexual advantages, black men are a more fit
competitor than white men. This explains why in cuckold practice, a black male
is usually chosen to be the extra male outside the couple. For the white male,
the black male amplifies the risk of sperm competition, since the white male is
not just competing with another male, but competing with another, more sexually
capable male. The certainty that black men are physically more capable is
confirmed in studies such as (Wilson et all, 2017), where they concluded that
white people see black men as stronger and more threatening than white men of
the same size. Based on the certainty that black men are physically and
sexually more capable, the biological response to this sperm competition, in
the form of sexual arousal, is expected to be greater, as a more capable
adversary requires a greater response.
Blacks and Whites: An Unfair Competition
The concept of
invasive species, or exotic species, is used to name species that are found
outside their natural habitat. Invasive species receive this name because they
have the ability to “invade” and dominate an environment, since they can find a
favorable environment for proliferation without predators and competitors. If
considering the Caucasoids and Negroids as competitors in the same environment,
to compete for resources and access to females, the Caucasoids would not have
to compete with the adaptive advantages of Negroids, since these developed in a
much more hostile and competitive environment. Although the dispute for
resources and access to females does not exist in today's society, the
perception of Negroid advantages is still perceptible to Caucasoids, causing a
certain threat, as described in the study by (Wilson et all, 2017).
Woman's interest in cuckold
The woman is the
centerpiece of the cuckold, it is around the woman that all the competition
between male instincts takes place. More than an object of dispute, the woman
has a decisive role in indicating who is the dominant male among the
competitors, and like the man, the woman is also subject to her own biological
mechanisms.
Women's preference for multi-partner costumes
In a survey, Baker and Bellis (1995) documented that 17.5% of British women reported having or having had a relationship with another man during the same period (regardless of their partner's consent). Large-scale surveys indicate that a significant number of women report polyandrous sex fantasies, imagining having sex with two or more men simultaneously: 18% in the United States (Hunt 1974) and 15% in the United Kingdom (Wilson 1987).
Similarly, several
smaller-scale studies have found that 15% to 41% of women report sexual fantasies
involving more than one man (Arndt, Foehl, & Good, 1985; Davidson, 1985;
Pelletier and Herold, 1988; Person, Terestman, Myers, Goldberg and Salvadori,
1989; Sue, 1979).
Rokach (1990) reported that although sex with more than one partner accounted for 14% of the sexual fantasies reported by a sample of 44 men, it accounted for 10% of the fantasies reported by a sample of 54 women.
Price and Miller (1984) report that polyandrous sex was among the 10 most frequently reported fantasies among college women.
In addition, a major study of sexual behavior in Great Britain, the National Survey of Sexual Attitudes and Lifestyles, conducted between 1999 and 2001 (Johnson et al., 2001) found that 9% of women overall, and 15% those aged 16-24 years reported having had sex with more than one man at the same time during the previous year.
Indicating that the
preference for FMM fantasies (one woman and two men) is greatest near the
ovulation period, this result presupposes an inclination to promote sperm
competition. Of the women who participated in the survey, 35% of respondents
rated FMM as their favorite fantasy.
The role of women in promoting sperm competition.
Bellis and Baker (1990) documented that women in committed relationships are more likely to be a double partner (a man other than their spouse) in the fertile period, when the probability of conception is greater. This observation suggests that women have psychological adaptations that actively promote sperm competition, with the result that their eggs will be fertilized by the more competitive sperm.
Gangestad, Thornhill and Garver (2002) documented that when women enter the high conception phase of their menstrual cycle, they are sexually attracted to and fantasize about men other than their regular partners. In addition, Gallup et al. (2006) documented that when they are in the fertile period, women postpone sex with their regular partner after they have had sex with another man, favoring intercourse with an out-of-pair partner, and excluding the main partner from sperm competition.
Thus, the sexual attraction of women to fantasize about men who are not their regular partner may indicate a precopulatory (before sex) female adaptation to promote sperm competition, and fertilization by the more capable male.
In this context, men
were adapted to have increased interest (sexual arousal) in their partner after
copulation with another male close to the ovulation period (Gangestad et al.,
2002), as there are still measures to be taken to prevent fertilization. male.
One such measure is the shape of the glans of the human penis, which has been
adapted to remove sperm from another male inside the vagina during intercourse
(Gordon G. Gallup Jr. et All 2013).
Women's Interest in Interracial Sex
Biologically,
fertilization and pregnancy cost a woman dearly, being months of gestation in
addition to years of caring for the offspring. Despite sperm competition,
naturally selecting the fittest male, due to the high costs of pregnancy, the
female is the one who has the greatest interest in selecting the gene that she
judges to be the best and most likely to survive. In this context, studies
indicate that interracial fertilization brings better benefits to healthy
offspring.
Genetic diversity is an essential factor for the health and survival of a species, and the lack of genetic diversity is the cause of several diseases (Alon Ziv, 2016). Therefore, interracial relationships are advantageous for the species, as they promote the genetic diversity of the offspring. Disgust for incestuous relationships is seen as a mechanism to avoid relationships between relatives, which would be the opposite of genetic diversity. There are studies that indicate that sexual fetishism for people of other races is a biological mechanism for boosting genetic diversity. The hypothesis is supported by the study by (Karen Wu et all, 2014), which concluded that interracial couples see their partner as more sexually attractive than same-race couples.
In this context, the black race receives an advantage, as blacks have the greatest genetic diversity among races (Baldo Lucchese, 2009). This genetic diversity reflects in greater adaptability to the environment, and resistance to diseases and other benefits (Michael C. Campbell, 2010), that is, interracial crossing with blacks promotes greater genetic diversity than with any other race.
The study by (Christian C. Joyal, 2014) reveals that 27.5% of women have sexual fantasies with interracial sex, being considered to have a high degree of arousal. Another study in 2015 (Christian C. Joyal, 2015) revealed that interracial sex is one of the most exciting fantasies for women. In recent years, in the annual statistics published by the PornHub website, terms associated with erotic videos with black people are among the most searched terms among women.
According to the
study (J Natl Cancer 1986), black men have, on average, 20% more testosterone
than white men of the same age, and according to (JE Schutte, 1984), black men
have 20% more minerals in their bones. . The study published in a book (Jon
Entine, 2001), which addresses the superiority of blacks in sports, states that
being black is like winning the genetic lottery.
A survey carried out in England with white female university students (Michael B. Lewis, 2010) judged the attractiveness of white and black male faces. Of the total, 100% of white girls rated black faces more attractive than whites, rating black faces as more masculine. According to the study by (Wade et al) black faces are perceived by women as more "appropriate" from an evolutionary perspective than men with fewer black features.
Sexual pleasure is one of the most relevant factors to drive interracial sex, since in our society black men have the stereotype of being sexually superior to other races (Emalydia Flenory, 2020). This stereotype has been documented from ancient times, as in Antoine Galland's compendium of stories from the Orient, One Thousand and One Nights, where Persian wives were reported to express their sexual predilection for black men. Studies published in recent decades confirm certain stereotypes, and serve as support for understanding biological predilection for black men.
Statistically, the penis of black men is larger than other races (Rushton, 2013) and (Pereira, 2004), being between 17.5 cm and 18.1 cm, while white men have an average between 13 cm and 14.5 cm.
A survey of women using 3D cylindrical models (Nicole Prause, 2015) concluded that the ideal size for female pleasure is close to 17.00 cm. Comparing the 2 previous studies, it can be seen that the average penis size of black men is closer to the size considered ideal by women than that of other races. The study by (Geoffrey Miller, et all 2013) revealed that women who prefer bigger penises are more sexually satisfied and have more vaginal orgasms than women who do not consider size important.
The study by (Baker and Bellis, 1995) documented that women retain more sperm from their partner if they have an orgasm 1 minute before or within 45 minutes of a man's ejaculation. The study indicated that vaginal orgasm (during penetration) functions as a selective sperm retention mechanism (Baker & Bellis, 1993b; Smith, 1984). Female orgasm causes the cervix to dip into the seminal pool deposited by the male resulting in the retention of a greater number of sperm, causing women to select sperm from partners who are sexually (Baker, RR and Bellis, 1993), and consequently, genetically superior.
A study of interracial relationships in an American college (Kita Lantman, 2005) indicated that most white girls are interested in black men, with 90% of respondents willing to have an interracial marriage.
In addition to the
biological factors mentioned above, in a purely sexual and rational context,
outside of evolutionary biology, a woman's propensity to practice cuckold would
be the double advantage of having sexual experiences with a male who is
physically more capable of providing pleasure, while maintaining the stable and
secure relationship with your spouse.
The role of the black man in the cuckold
According to (Rushton and Bogaert 1997), Negroids have adapted to the r strategy, where there is a large number of copulas with different females and low investment in offspring. This behavior fits perfectly into the practice of cuckold, where the black man can copulate with different females (the couple's wife) without demanding efforts to care for the female or the offspring, although nowadays, it is rare to hear about this type of fertilization in cuckold practice. According to Rushton, the larger testicles of black males compared to white males reflect an evolutionary behavior based on the fertilization of female multiplicas. The advantage of testicle size is magnified with the presence of a different female, as according to the study published by the scientific journal Springer in 2015, men greatly increase the volume and quality of ejaculated sperm when exposed to different women than those already known. In addition to the esteem of the different female, the pleasure of imposing her dominant position on another male can generate advantages for the chances of fertilization, as the study by (Pound, 1999; Zavos, 1988) found that the number of spermatozoa increases in relation to the level of sexual arousal.
In the cuckold context, the black male assumes a dominant role exercising the female's monopoly, who in turn recognizes him as a more capable male than her spouse. It is a privileged role because, as he does not need to have resources for the female, he has more resources to invest in his own development and maintenance of dominant status.
In cuckold, the black man occupies a privileged role, since by building masculinity in today's society, he sees him as virtuous, exposing that he practices cuckold and has relationships with the wife of a couple. This causes an accidental aspect of the cuckold, since the fear of being exposed or a possible shame in the practice of the fetish tends to drive the couple to have a more passive and collaborative attitude towards black people, elevating the black man to a role dominant not only in the relationship with the couple, but also in society.
In communities of
cuckold practitioners, it is common to see the term “fixed black”, or “regular
bull”, being the term used to designate a black man who regularly has sex with the
couple's wife (Adrienne D. Davis, 2019) . Specific. With this type of
relationship it is common to see elements of BDSM, with the couple taking the
role of "submissive" and black man the role of "dominant".
As the cuckold community grew, its own terms and symbols were developed. The symbol "Queen Of Spades" or "QOS" consists of the "Swords" suit of the deck with a letter "Q" inside it is used to inform couples who are practitioners, normally used by women, as a way of informing that this women have a predilection for black men. Although this symbol was developed as a form of hidden message for social identification, facilitating the meeting of couples with black men, the symbol is widely used as a way to demonstrate submission to black men.
It is common for cuckold practitioners, or men who yearn to practice it, to have fantasies in which the practice of cuckold is common in society and for all women to realize that black men are physically and sexually more capable. than whites, since this scenario represents an environment of extreme competition.
The sperm competition hypothesis gains strength with the developments of this fetish, such as the practices of the “creampie”, (Emalydia Flenory, 2020), where the peak of the white man's pleasure is to verify that the black man's voluminous sperm load has been deposited inside your spouse. Despite contraceptive methods, this act clearly alludes to the successful fertilization of your female by another competing male.
A hypothesis that can
still be considered is that the cuckold could be an evolutionary mechanism for
the propagation of the species, not the individual. In this scenario, some
biological mechanism could be driving the white man to disregard the continuity
of his own offspring, since by allowing the copulation with his partner, the
white man would be instinctively promoting the general improvement of the
species, through the benefits of interracial crossing , providing diversity,
added to the genetic advantages of the black race.
Why is cuckold becoming so popular?
According to internet statistics (Google Trends) there has been a steady increase in interest in cuckold since 2006. The increase in interest in this period coincides with the period of dissemination of broadband internet in the USA and the beginning of the operation of adult content sites with xvideos, pornohub and others, which allow users to upload videos and make them available online. The most likely hypothesis is that as cuckold practitioners began posting their personal videos, more people felt drawn to do the same, intuitively being pushed to experience the same sensations. As a result, there was an exponential growth in the practice, as indicated by statistics (PornHub insight, 2016). It is highly likely that on the home page of any of the major internet porn sites, some video displayed as "most popular" is interracial cuckold. The search for the term “wife” itself returns results directly linked to the practice of cuckold, indicating the content preferences of users.
The popularity of the
fetish has shaped the markets for pornographic production, with major studios
focused on producing cuckold and interracial content such as
"Blacked" and "CuckoldSessions". In addition to
professional content, the practice of cuckold has expanded the adult content
market to new niches through authorial content. Large adult content streaming
platforms have created mechanisms to monetize professional quality amateur
productions, making it possible to have high incomes through homemade
pornographic production. Due to the high popularity, it is easily observable
that most monetized videos are cuckold themed, leading more and more black
couples and men to look to cuckold as a means of earning income.
Why are more and more young people practicing cuckold?
With the popularization of smartphones and access to the internet, young people have had easy access to pornographic content, whether on their own initiative, by third party induction or by accident.
The institute (Institute
Bravehearts, 2013), collected and analyzed information from a variety of
American surveys, and found that 90% of teenagers aged 16 and under claimed to
have seen pornography on the Internet. In developed countries, about 75% to 90%
of teenagers have seen pornography on the Internet before they turn eighteen.
In Australia, 93% of men aged between 13 and 16 and 62% of women were found to
have seen pornography on the Internet.
A survey carried out in Sweden (Christina Rogala, 2016) found that 84.4% of young women aged 14 to 24 had used pornography and 80.3% believed that pornography influenced their behavior in relation to sex.
According to the data (Institute Bravehearts, 2013), viewing pornography at a young age can influence an individual's sexual behavior throughout life. More than half of the men included in the study aged 16 to 24 years reported that pornography influenced their sexual behaviors.
The consumption of
pornography by young people is associated with more permissive sexual
behaviors, such as relationships with multiple partners (Institute Bravehearts,
2013). In addition, exposure to pornography at a young age has a permanent
impact on an individual's sexual behavior, as this is when the brain
connections of association, pleasure and reward take place (Donald L. Hilton,
Jr, 2013). Once the neural connections are established, they are unlikely to be
changed. Considering the susceptibility of the practice of cuckold by
biological mechanisms and the abundance of cuckold content on pornography sites,
it is likely that young people exposed to cuckold content, have their brain
connections of pleasure and reward associated with the practice of cuckold.
