This kind of attitude of "It's only cheating if..." perpetuates the "only straight sex is real sex" mentality. It eliminates the validity of non-straight sex and relationships, with the cool addition of trying to find a relationship loophole in order to cheat. It shouldn't even be a question -- if you are in a monogamous relationship and you are having sexual or romantic relationships with ANYONE other than your partner without their expressed knowledge and approval, it is cheating.
In short... yes, cheating is cheating.
Edit: Sorry original poster; I did not mean to make this sound like it was directed at you. It's just a touchy subject for me.
