I enjoyed reading it highly. Some guys don't like the strong evidence it shows of women being born to be promiscuous because it makes them question why they arn't getting laid enough themselves. Not you OP, I'm sure.

I love the nodding agreement you can get when telling girls on a date that 'vocal projection' during sex by women was developed as a call to more males to fertilise them. "That makes so much sense!"

Not as wise to mention the penis head having a ridge (and combined with thrusts) to scrape out other mens sperm...
