My boyfriend and I have been sexually active since January. Only one time has he been able to get me to orgasm and its really bringing him down every time we have sex lately...
He's about 5 inches or so and he thinks its because of his length that I cant seem to orgasm during sex. I keep trying to tell him he's pretty much the perfect size for me (Im completely comfortable with his size and actually I quite enjoy it) and that I dont think he needs to be any longer or needs any kind of male enhancement or anything like that. He knows that Ive only ever really been able to orgasm through masterbation and hes even tried to do that with me and it hasnt worked. It seems like Im the only one that can do it to myself pretty much..
I dont know what to do. Im trying to convince him that its not his fault and that its mine. I dont know what my issue is though. Ive come close to an orgasm several times in certain sex positions, but never actually got to it. Its like it slipped away from me all of those times.
How do i convince him its not his fault that I have a hard time with it and what are other things we can try to help with it?

And then second..theres anal..
We've tried anal before..and didnt get very far at all. I'm open to the idea of it..its just that Im still a little fearful of the things that could go wrong during anal...such as really embarrassing things..
I'm open to the idea, like I said. He would just have to try to work me up to it..
He really wants to try it and hes a little upset at how much it hurts me and makes me uncomfortable.
I do want to get to the point where we can at least try it, not only for him but because who knows..I might enjoy it.
I dont know what to do or say to him about either anymore...
Help/Advice would be great.
