Hello! This is my first time posting here. I'm just wondering if you guys have the same experience, or if I'm not normal? You see, when I get fucked by a big penis, on the way out of my ass, I tend to fart sometimes. When I fart, I can't seem to enjoy the sex anymore, so I just tense up and it gets really uncomfortable. This is also the case if I finger myself with three or more fingers, although I don't tense up, because it's just me. Anyway, am I doing anything wrong? Is this common when having sex? Oh, and I'm a gay guy, I guess that's relevant.
