I think we have our monthly winning post for the I just pulled something out of my ass award. While it is true that most men I know have sought out as many female partners as possible, it is absolutely untrue that they were doing so in the name of impregnating them. Especially impregnating them all.
So you admit that males seek to sleep with as many females as possible. Why do you think that they do that? Couldn't be natural instinct could it? And why do you think they don't want to impregnate them? Did cavemen care if they impregnated every woman that they had sex with? Hmm, I wonder if the rules and penalties of society have anything to do with it?
I also find it hilarous that in your argument for what is normal and what is not you gave an example of a man with 30 kids as normal behavior. Is your last name Duggar by any chance?
No, I gave a man with 30 kids as an example of human natural instinct to reproduce.
