It's all in your perspective isn't it? For example, I'm bisexual and happily married. If I want to flirt and play a little with a woman, my husband doesn't mind, in fact he encourages it....so it isn't cheating. By the same token, if I have intimate, soul-deep conversations with anyone else (man or woman) my husband would consider it cheating. Cheating is always going to be subjective and can only be defined by the two people in the relationship.
