My boyfriend is 21 and I was his first. He tells me that his penis is very sensitive. If I stroke him he says it hurts. If I give him oral sex it hurts. When we have sex he says that I'm too tight and it hurts him. Is this normal or is there a problem? I've tried to be gentle with him, I've even used a lubricant to make sex easier for him. He still complains about it. I told him that he should see a doctor to find out why it always hurts. He refuses to see one. What should I do?? 

First of all, find out if he can masturbate successfully. If he can, then there must be some way of solving this pain problem, or there is something else going on and he is using this "pain" as an excuse. If he can masturbate, ask if you can watch him. Perhaps you can copy the motions he makes with this hands.  If it seems that he is not being particularly gentle with himself, then perhaps he should go to see a sex therapist. As I said, maybe he has some other fear and just does not want to have an orgasm with you and is using this "pain" as an excuse. It is possible, though I am not saying it is likely, that he is gay and won't admit it. He may not realy like being touched by a woman, and rather than tell you this, pretends to be in pain. This is just one possible scenario, and since there are many other possible reasons, you must see a professional to find out what can be done.
