I love my boyfriend, and we seem to be completely compatible on everything except for this issue. We have tried a few different forms of sex (vaginal, oral, anal) but he doesn't seem to really enjoy any of them. He said it just feels like "air" when we are having intercourse and that he doesn't get off to fellatio (or at least the way I give it to him). I am the only person he has ever had sex with, so I have no idea of what to go off of. I have only had sex with one other person, so I can't imagine that both my vagina and anus are that wide. He thinks it might have something to do with the fact that his penis does not fit all the way inside my vagina (he is 7.5 inches) and if that is the reason, I don't know what to do. Ironically, he is able to orgasm but it takes a lot of time, and if he isn't enjoying that time I'd rather spend it doing something that he will really enjoy. I just don't know what. I'd really like to bring him more pleasure and keep things going great. Please help.
