Everyone can deny it if they want, but males have sex mainly based on opportunity.It certainly explains why so many guys I know seem to, as I have otherwise put it, invest a lot of emotion in girls they really have weak (or non-existent) emotional bonds with.
Especially interesting is the contrast with the video asking women for sex. The men seem to be kept from agreeing only by their suspicion, if at all, whereas the woman react with outright mockery or disgust.
Yes, it was a perfect and simply social experiment to show the fundamental difference in the sexes approach to sex. It comes down to gametes. Sperm is free and not valuable. So when men are in a situation where a woman just really wants their sperm and nothing else they jump at the chance. Of course this situation never actually happens because women behave by their own evolutionary logic. In contrast, eggs are certainly not free so a woman will not just give them to a man "for nothing" - hence the mockery/disgust.The men seem to be kept from agreeing only by their suspicion, if at all, whereas the woman react with outright mockery or disgust.
