You know, all the stuff that women want as well. Good looks may start the relationship, but they won't sustain it. It takes an emotional bond to hold things together. Bad boys may expose these women to things they wondered about. But usually this is a sign of immaturity, and as the woman gets older and her goals change the bad boys start to look immature and silly.
Sex becomes a ritual, and often only about getting an orgasm.
So women like the other sexual aspects of caring, and you should to. I often recommend that couples have no-sex makeout sessions to rediscover the thrill. Or it could be that she needs her toys to have and orgasm. It's important that the two of you be able to talk about this openly, rather than trying to guess what's going on . Good sex is about communication.
