As a guy my rule is if i don't know the girl's bf/husband then she's fair game and i couldn't care less about him except if he was a dangerous guy and could potentially fuck me up (criminal, ex-criminal, drug dealer etc). I want to know the female view on this. Assuming you were in high school, college, professional world or wherever you are at life and you are attracted to a guy he wants to sleep with you as well, would you do it knowing that he has a girlfriend, fiancee or wife? Lesbians and bisexual women of PPD can also answer. Would you do it knowing fully well that a girl you're attracted to has an SO?

Yes or no?

What are your reasons?

Do you think you owe the woman any loyalty?

Kissing, flings, having sex etc with the person who didn't disclose he/she has a girlfriend or wife or you weren't aware of doesn't count. I'm asking if you would or have done it KNOWING fully well that he/she is taken?
