This article pretty much sums up everything written in the PUA community. Based upon a study examining women’s brains response to images of men with more and then less masculine features, women, at certain times in their menstrual cycle, prefer men with high testosterone, while at other times they prefer men with obviously lesser testosterone. The high testosterone men are preferred during ovulation, when sex desire is at its highest in women and the genetic strength of their offspring is their primary concern, while men with lesser testosterone are preferred at non ovulation times, when women are more concerned about the pair bonding and having someone around to take care of the kid.
As a high testosterone man myself, I can personally testify to how many women viscerally respond to unabashed manliness. A drenched pussy is all the scientific prove I have ever needed, but it is nice to have some outside confirmation of my own scientific endeavors in the erotic world.
