I wonder my boyfriend gay or bisexual on the low or suspect?

Idk if I’m tripping but I know I’m not slow it’s been multiple times that I have scratched my head and wonder about my boyfriend and his sexuality he has always in the past and I’m pretty sure want to have anal sex with me but I can never bare the pain which kind of made me wonder then we have a roommate and he is ok having his shirt off around him idk maybe I’m tripping but I just don’t know at this point I need advice what do y’all think ? Other than those two things that’s the only things that made me wonder plus I have heard gay rumors about my roommate at work but I don’t listen to them idk I just wonder sometimes is that a bad thing? I don’t think he’s gay but I do wonder
