Ehhh, this is probaly not the best forum to even talk about relationships on. At a certain age, sex is generally expected. FOR BOTH SEXES, don't give me that male's are sexist pigs bullshit. However, if a girl doesn't want to have sex in a relationship, there is nothing wrong with that, and a guy should never force a girl do anything she doesn't want to. Also, dating for wives at our ages fucking retarded.
Date for fun. live for fun, you're young, enjoy it goddamnit.
