The first 3 have chilly testicles, which increases sperm production. They are meant to be used to take part in sperm competition with other males, having sex with the same female.
The head of the human male corona is extra large and works as a squeegee to scrape out another man's semen. Not mentioned in the book is the idea that women's watery ejaculate is produced to wash out semen, to make way for something better that just came along.
Loud female vocalizing during orgasm is a mating call to attract other men. "Ooh! Someone's in the mood." She is multi-orgasmic, while most men are good for just one shot (at least for an hour or so). So, the first guy or 2 are just warmups.
So in an orgy situation where pregnancy is the goal, the third guy in line needs to have a huge head, not have cum yet, and the woman needs to be thoroughly cleaned
I have read about the head before, as well as the multi-orgasmic part. And of course the loud orgasming part, that ones I think obvious to most people
However Thats a new one for the ejaculate. thanks..
