I think I agree with the person who said there was no real definition of this, I think it depends on the person and the spouse/other half. My husband has always said that sexual intercourse is cheating, that's it. Now I'm sure he doesn't expect me to go give 100 blow jobs and not be pissed off about it ( I wouldn't do that anyway lol)

Different for everyone I guess.

My definition of cheating is a little more complex then that, I think cheating can be done with your mind as well as your body. But I'm religious and I think that has a lot to do with it.
