The Female Orgasm, Are Men The Key To Unlock Its Mystery?


Sketchy theories abound, but they don't consider how her orgasm affects her partner.

Female orgasm has remained an evolutionary enigma. Even the most promising theories about it have a nasty habit of collapsing under the scrutiny of scientific investigation. [1]

One thing that has been overlooked is the effect that female orgasm has on the male partner. Yet this might be the missing link that finally sheds light on the evolutionary function of female orgasm.


  • Her orgasm during sex tends to arrive much later than his, on average. The famous Masters and Johnson study "found that men took about four minutes to reach orgasm with their partners. Women took about 10–20 minutes..." [2]
  • Women often moan during sex in conjunction with their partner's climax rather than their own. A recent study found that "many of the women did make noise, but not necessarily while they were having an orgasm. Instead, 66% said that they moaned to speed up their partner’s climax... While female orgasms were most commonly experienced during foreplay, copulatory vocalizations were reported to be made most often before and simultaneously with male ejaculation..." [3]
  • Men are the primary consumers of porn [4], while women are much more likely to use vibrators [5]. In other words, they're turning to technology to fulfill different needs. She uses it for direct physical stimulation, while he craves exposure to other human beings in a state of arousal / orgasm. [6].

So her orgasm tends to arrive later, but it has a decided effect on him, one they're both conscious of. Is it possible that her orgasm facilitates his, in cases where he hasn't quite gotten there yet?

Perhaps the evolutionary nudge that selected for the human female's happy ending is the human male's propensity to get off on it.
