Almost all women are completely wrong about why men approach women.
Especially these days, women believe that men approach them because they think the men expect to be having sex 10 minutes later. This is false for nearly (99.9%+ all men).
For most men (and I cannot stress this enough), talking to a cute, interested girl is the fun.
Anything that happens after that is great, sure. But it’s not the reason. It’s amazing for all that women claim to understand men1 that they do not get this.
