Ever since my first time having sex until now (approximately 5 years) it's always hurt. I always keep my hand down there to kind of prevent my partners penis from going all the way in. When it does I get incredibly sharp pain. Also to mention I hardly ever get wet.. I don't know why. I've been to and OBGYN about this before and all they could say was maybe your body is not entirely not in the mood. But I feel like it is. Please advise!
