Humans behavior does not seem to be driven by basic urges anymore. If men wanted to make as many women pregnant as they could, a business of impregnation tourism would have sprung up where women in poor countries would be paid to have the children of wealth men. Men would have no interest in an sexual act other than PIV. Men would leave relationships as soon as the woman was pregnant. No couple would ever adopt.
People don't in general act like that. The motivations for modern humans are far more complicated and survival of ones genes is only one of the many things being optimized.
our primordial drive and attraction in a mate is still based on the ideal of making babies, but the acts themselves are more complex. We are no longer a fish in the ocean squirting sperm on as many eggs in the rocks as possible, but we still have that foundation in our sex drive.
sex is more of a social bonding and communicaiton system than anything. we want sexual acts other than PIV because it shows commitment to someone else and committment from them to us.
Men don't want to dedicate resources to a mate that doesn't want them because then they are just a cuck, and women don't want to put out for just some guy who won't stick around. However, if the man can plant his seed in some girl for the moment there is no risk, and if a woman can go way out of her league with a one night stand can get a prized seed she will do that while still lookingf or that ideal knight who will save her. Women have two contradictory goals, men have basically one goal which is to spread the seed. However, when logic is applied over instincts, women and men will both pick mates that are loyal and comitted. However, hte instincts often drive the decision more than logic.
Men look for looks, and overlook personality, women look at looks and overlook personality too, but they also look at the traits mentioned above. Also, women want a son who is a seed spreader too, so if they find a man who has those personality traits he is desireable. thats why men are socialy more allowed to be ****s while women are shunned.
men don't want to be a cuck, so the ****tiness might be fun for a ngiht but men will move on quickly and won't dedicate resources to that girl as oyu cannot gurantee offspring produced are your own.
