How Social Constructionism Created the Sex Addiction Model

Imagine it is the year 1965, in frozen Winnipeg, Manitoba. Two twin boys are scheduled for routine circumcisions. Using an unconventional practice known as cauterization, one of the boy’s penises was accidentally burned beyond repair. Dispirited and confused, the boys’ parents were watching late night television one evening when a charming, well-spoken psychologist appeared on the air.  Sexologist John Money claimed he had discovered, through his “theory of gender neutrality,” that gender was a complete social construct, created entirely through social learning. Emboldened, the parents contacted Dr. Money, who ordered sex reassignment surgery for the injured boy, and instructed his parents to raise him as a girl. Because this surgery occurred at such as young age, the (now) girl would never realize she had once been a boy and would live her life as a normal female. Money touted the success of his work, publishing extensively on his triumphant results. However, eventually the truth came out. The young boy never acclimated to being a girl, and eventually as an adult sought to transition back to being a …

Why Did Humans Evolve Big Penises But Small Testicles?

Humans have a much longer and wider penis than the other great apes. Even the largest of gorillas, more than twice as heavy as a human, will have a penis just two and half inches long when erect. However our testicles are rather small. A chimpanzee’s testes weigh more than a third of its brain while ours weigh in at less than 3%. The relative size of our penis and testes is all down to our mating strategies, and can provide some surprising insights into early human culture. Primates exhibit all sorts of mating behaviour, including monogamous, polygynous — where males have multiple mates — and multimale-multifemale. One indicator of which behaviour occurs in a species is the size difference between males and females. The greater this sexual dimorphism, the more likely the mating is either polygynous or multi-male to multi-female. This can be shown by observing chimpanzees and gorillas, our closest living relatives. Male chimpanzees are much larger than females, and they have a multi-male to multi-female mating system. Essentially, male chimps have sex all the …

Interview with Debra W. Soh, Sex Neuroscientist

Meet Debra W. Soh, a sex researcher and neuroscientist in Toronto, Canada. I learned about Debra through reading her LA Times op-ed on the futility of gender neutral parenting. I got in touch with Debra because I wanted to learn more about her field of sex neuroscience, her own research and her thoughts on studying sex differences in the brain. Because the study of sex and sex differences is often fraught with political roadblocks, I also wanted to get a picture of how a neuroscientist-sex researcher approaches some of these contentious issues. Hi Debra, thanks for chatting to Quillette. Can you briefly tell us who you are — where you studied, who was your supervisor and what made you interested in neuroscience, in particular sex neuroscience? I am a sex researcher at York University in Toronto and I write about the science of sex for several media outlets, including Playboy. For my PhD, which I just defended, I worked with Dr. Keith Schneider, who has pioneered new methods in high-resolution fMRI and is the Director of …

What’s the Point of Sex? It’s Communication at a Biological Level

Most people think just one sperm is needed to fertilise a woman’s egg and make a healthy pregnancy. This underpins a common view that all the other sperm — and all the other sex — are surplus to requirements, at least when it comes to conceiving a pregnancy. However, biologists now believe sexual intercourse is not just a sperm delivery process, but also a kind of biological communication. Regardless of whether fertilisation occurs, sperm and other components of the ejaculated fluid trigger subtle changes in the immune system of women. This has consequences for pregnancy should it happen later. More broadly, the importance of regular sexual activity also has implications for fertility planning, and for IVF and other forms of assisted reproduction, which generally do not take sexual practice or history into account. Sperm swim in a soup of molecular messages Evidence from animal research and clinical studies has led researchers to conclude seminal fluid — the fluid sperm are bathed in following ejaculation — plays an important role in fertility. Seminal fluid contains small molecules that act …

Not My Rights Movement

Currently, LGBTIQCAPGNGFNBA is believed to be the world’s longest acronym used to describe human sexual orientations and gender identities. Chances are it’s already been surpassed by an even longer acronym with the self-discovery of yet another person, or group of persons, with a unique gender fixation. It’s probably pointless to try to memorize what all the letters stand for, because theoretically there’s no limit to the proliferation of sexual identities. But some of them come with unique pronouns, and you had better learn those. Otherwise you might run afoul of new federal and provincial human rights and hate crimes laws. How on earth did we get here? Well, in the beginning there was G. And it was good. I’m not talking about God but about Gays. Back in the early 1980s, I joined the fight for gay rights and marched in the Toronto Gay Pride parade. Before G, there was actually H, for Homophile, as in the Queen’s (University) Homophile Association, which I discovered in 1978. I have to admit I welcomed the change from …

To Rape is to Want Sex, Not Power

In the 1975 bestselling book: Against Our Will, the feminist writer, Susan Brownmiller, asserted that “rape is about power, not sex.” Ever since, the conventional wisdom has been that rapists are misogynistic men seeking domination and power over women, not violent men seeking sex. However, there is a fundamental problem with Brownmiller’s bold assertion. In the ensuing 45 years, there has been no significant empirical research to support her claim. Yet, almost everyone repeats it. In examining eight years of FBI data on 250,000 rapes and other sexual assaults, one factor stands head-and-shoulders above the others: the age range of the victims. Herein lies the key to unlocking the mystery of the offender’s motivation. Social science has demonstrated a strong relationship between age and sexual attractiveness. Heterosexual men are sexually attracted to young women, while homosexual men are attracted to young men. The age preference explains why adult film stars, sex workers, exotic dancers as well as glamour models are often young, and why their earnings decline as they age. Studying the ages of victims, …
