I agree.

BUT,
cheating implies that it was a monogamous relationship. It's not really considered cheating if its an open relationship in some way, like what seems to be the case with a lot of the posters here...so if everyone involved is ok with it, then go for it.

Anyway, I don't understand why a thread about bisexuality has become "Let's share stories about how we are with both genders even while in a relationship. Hooray stereotypes!"
