I've been lurking this subreddit for awhile and there seems to be lots of useful info here. The one question I have is about men's biological sexual needs. Where is the scientific study that has proved that men are genetically hardwired to want to spread their seed and sleep with as many women as possible?

I asked this question on askreddit but no one could show me any real proof of this. One person said it was just common sense but common sense usually has proof, which is what makes it common sense.

I would like to see links to this study or links to scientific proof.
