Where do I draw the line?

Although we have tried having sex quite a few times, my boyfriend can't get an erection. I know how much it bothers him and I'm trying to be as supportive as I can but I'm not sure what to do now. The only thing that seems to work (albeit marginally) for him is giving him oral sex, which I personally hate doing. I don't like doing it and I don't like having it done to me. I should have just said no from the outset but I think I was afraid I was the reason it wasn't working. Although he insists it's not me, and he's going to see a doctor this week, sex with him makes me feel insecure and generally just ... bad. I'm very attracted to him and I want to have sex, but the whole thing has just become so stressful and disappointing for both of us. I feel awful because it's got to be just as bad (if not worse!) for him, and I know that he feels terrible about this too. I've started dreading sex because he's come to expect oral sex, and I'm not sure how to tell him how much I hate it when it's the only thing that works for him, and when he's been careful to satisfy me in other ways. I know how much he likes me to go down on him but the whole thing disgusts me and I find it's a huge turn off, especially when it's not even working. I have no idea what to do about any of this now. I could really use some advice!

Your boyfriend going to the doctor is the best thing. My husband went to the doctor for the same problems and found out he had medical issues that had to be taken care of. Talk to your boyfriend about how you feel. I know it will be uncomfortable for you but you are uncomfortable right now with the way things are. It will eventually affect your relationship with you doing things you don't like to do.
