can't take it

my boyfriends parents came down to see him last night and he feels weird having sex when his parents are right in the next room. (his apartment is really small so the living room is right there) but I feel like we can be quiet enough and it's killing me that we can't do anything since he doesn't want to. I want to just suck it up and respect him but at the same time I don't want to and I don't know what to do.
