LOL!!! Me and Brad have been together for 5 years and I have only farted in front of him once...and I was 9 months pregnant. So I really don't count that because when you are pregnant its hard to hold them in enough to make it to another room.
if you can have sex with your b/f or husband, or whatever, you can fart in front of them! Sex is the most disgusting act! If your s/o thinks it's nasty, screw them!
I fart in Matt's face all the time, and trap him under the covers when i fart!
