It behooves the smart woman to find out what kind of man you are, prior to hopping in the sack.
4) INTIMACY - women want to feel connected and close in order to have sex-how close to you can she feel if you are trying to get her to drop trou for you in the men's room so you can get a quickie.
Unless you are trying to hop on a bar ho, a woman of quality is not going to just give it up to the first guy who says hello. I wished we lived in a climate where people could accept that sex doesn't devalue a woman, but until that time comes, women have to be careful.
3) REPUTATION - yes, even in this day and age, a sexual woman is scorned.
Many women feel that in order to be taken seriously, you can't give in to every urge. It is a sad fact that women have to worry about such things when men do not.

You have to decide that you'll do whatever is necessary to get a handle on your dating life.
