Cheating on someone or with someone, hooking up with your best friend's ex, a co-worker, or the person that your friends and/or family don't approve of would all be considered forbidden sex. I've had a few scrapes with this, but I should stick to fantasizing. Forbidden sex is forbidden because someone, somewhere, will be hurt.
