What else is there?

My boyfriend (32) completely hates anal sex, giving or receiving, though he is the more "dominant" one in the relationship. I (23) get upset a lot because my boyfriend worries that we will run out of things to do in the bedroom or it will get too boring too fast, and I hate to even try to agree with him on that standpoint - I try to keep an optimistic attitude in this struggle with him. His words do get me thinking though, what else is there in the gay world to do with anal sex out of the picture, disregarding elicit drugs, that hasn't really already been done? I need help, and I need ideas - fast.
