I've never had problems with people knowing I have stomach problems (boyfriend, parents, work colleagues). I am actually also recovering from anorexia and that was much harder to deal with. I've also had severe stomach problems and tendencies to bloat and have diarrhea since I was a kid, so maybe I'm used to it by now. My boyfriend is fine with it, even when I get bloated and turn into a fartmonster from the arse lagoon!
I've never really dated, however, just had two long-term boyfriends...
