Women seek emotional connection before sex men rarely do that.
There are 3 major reasons behind it.
1. Women have potential of getting pregnant so they seek connection because they want commitment instinctively. If they get pregnant and can't get commitment they couldn't survive millions of years ago in the wild. So women evolved to seek connection from a man so she can get commitment. That's why women get really upset when a guy don't call or text after sex. Because instinctively they want relationship.
Women aren't like men they don't need to fuck a lot of men they seek quality not quantity. They want to get the best guy they can get and want to be in relationship with him.
2. Women don't desire a guy based on 100% visual factors. Yes they are visual they look for visual signs but not like men. They also want to know if a guy is confident enough. Because a man's value comes from survival potential and having confidence, having masculine traits is so important for that. So women has to know the guy little bit to see his truth personality.
3. Women were in great danger always. Even today they get beaten, they get killed unfortunately. Having sex with someone you don't know well is very dangerous, very vulnerable position specially for women. They can be kidnapped, they can be killed, they can be sold, anything can happen. We can't relate with women because generally men are stronger than women. We don't think like that. So women seek emotional connection, they seek trust. They want to trust you about you will be nice to them.
That's why women seek emotional connection before sex even if it is a simple hook up. They always seek trust first. They always want to know you before sex.
