My boyfriend is moving in and I'm worried because I have irritable bowel syndrome?

I try not to use the bathroom around him, but he's moving into my apartment and it's small so he's going to be around when I use the toilet. Anyway I have irritable bowel syndrome and sometimes when I poop I flatulate loud farting noises as the feces is exiting my colon. I'm nervous because I'm sure he'll be able to hear it in the other room and he won't think of me as y any more...can someone pls give me some advice? thank i know this is a weird question but its seriously been on my mind
