Male orgasms make men want to have more sex so that they can pass on their genetic information—that’s why almost every male species has orgasms. But female animals don’t need orgasms in order to pass on their genetic information. In fact, some female animal species don’t have orgasms at all (the poor things).
So biologists began to wonder, “What role do female-gasms play in evolution? And if they do play a role, why are they so much harder for human women to achieve?”
Some behavioral scientists think that female orgasms indicates male’s virility or strengthen the emotional bonds between sex partners care so that both parents care for their children as a team. But scientists say if female orgasms do serve those important evolutionary functions, you’d think they’d be much easier to achieve.
For a guy to get off, all he has to do is start thrusting his junk into a moist hole (just about any will do). But female orgasms require more than just mere penetration—they require clitoral stimulation; something that doesn’t always occur during procreative sex.
Some evolutionary biologists think that women simply have orgasms because they share the same genital tissue as men. In utero the same tissue that forms into a man’s glan penis can also form into a woman’s clitoris; hence female climaxes could just be the by-product of shared bodily material (ie. the same reason men have non-lactating nipples).
But a recent study of 1,803 opposite-sex twin pairs showed that even siblings with the same genetic makeup still vary in how often and how easily they reach orgasms.
That’s not to say that female orgasms don’t play an evolutionary role, scientists just don’t know which role they play yet. But don’t let that keep you from enjoying them all the same.
