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, …
