It's not as bad as you think. At least, when it's a girlfart it's not as bad you think. I hold mine in when my wife is going down on me, because I'm afraid doing it once might end all blowjobs for a long long time.
Are gay farts more like girl farts or guy farts? i just realized there might be something about dick chasing lifestyle that makes them not be so bad. Or alternately, something about the pussy chasing lifestyle that makes them rancid, but we don't have any dykes around that we can poll.
