Ever seen the movie "Chasing Amy"? In that movie, the girl broke up with a guy because he farted while she was giving him head. He tried to explain, "but I was feeling so relaxed, it just slipped out." Maybe your oral is just so relaxing to him he couldn't help himself?
Why focus on the worst version of what happened?
I sometimes tell my W, "If I say something to you, and there are two ways you could take it, good or bad, I meant it in the good way."
ricsgirl, you need to forgive him for sleeping on the job (heh heh). Really. You're holding a grudge. Give him the GIFT of forgiveness.
