The issue is intimacy. You can't categorically blame men for this because a lot of people do not have this experience with men. However, you end up with certain types of men consistently, who do not value your personality, which is probably because you do not express your personality enough. I'm guessing that you probably hold back a lot of assumptions and expectations but you don't assert yourself and communicate what you want from a man. So you get men who pay you lip service just to get you in bed.

Probably you intimidate more honest, normal men because to them you seem unavailable because you are not advertising your availability, only reacting and responding to whichever men end up trying to manipulate you.
