I have been with my boyfriend for 8 months now! We performed foreplay twice. Every time I mentioned sex he had an excuse for not doing it. We have not had sex yet. He has pushed me away so many times. It really does make me feel un attractive and unwanted. It came to the point when I ask if he was gay! He shouted which led to an argument. I walked out. He later text me and told me he has a problem he is so embarred and does not know how to satisfy me. He has no confidence what so ever. What can I do? We all know what it is like, do I just jump on him or what? I'm to scared in case he pushes me away again!

This is an issue you work out by trying and talking and trying,
He also of course can and should have a complete medical check up.

I agree with Fr_Chuck practice and things will eventuallly work out.

It doesn't sound to me like a medical problem, it sounds like nerves. I'm guessing he has not had sex before and is probably terrified of doing it wrong. The best thing you can do for him is show him what you do and don't like. Start by massaging each other, letting each other know what feels good, and go from there. If he does something that feels nice, let him know by either saying so or moaning etc. If he does something that hurts, guide his hand away. Take your time and these things will come naturally to you both
