I get extremely turned on by jealousy. The thought of my girlfriend cheating on me without us discussing it gets me extremely jealous, and results in these strong feelings inside of me, which lead me to pleasure myself. I actually strongly enjoy the feeling of jealousy, I don't know what it is. The fact that I don't think my girlfriend would ever do that, because she is not that kind of person at all makes it seem even stronger. I would feel very uncomfortable asking her to cheat on me though.
