Are you in England? If you are I can't help you personally; American. How old are you? It would seem that you might have a dislike of men. It is very common; too many men are pigs. What you ought to do, is not go out with just anybody. Wait for someone you really care for, and develope a relationship. Many women only want sex with those they have feelings for; this is another area that men and women differ.
WAIT!
