Why does sex still hurt, even after the first time?

I have sex with my boy friend and the past few days when we do it, it still hurts I thought only the first time only hurt. So why is it still hurting me when we do it?

Dear rf007,
Well it shouldn't hurt...perhaps your sex play is a little rough, too often, too long? When first getting into a sexual relationship tenderness is required. So maybe slow down, don't do it so often and shorten the intercourse durations. If you find that it is still painful see a doctor. Love making shouldn't hurt.
Sue...good luck
