Haha Im really anal (pun intended) about stuff like that, so it probably would get to me.
Ive broken up with girlfriends before simply because I saw them throw up and it put me off, but my current girl and I have been together for 8 months so I think Id be strong enough to work through it. Throw up girl was about 2 weeks to a month.
Id definitly clown her about it though
But how the fuck do you forget to flush anyway?
