Is it okay to have sex with partner when you know he/she loves another person?

Sex isn't just a thing that you just do... When there's a relationship tag attached to it, it's emotions. Not just an activity.

I wouldn't have sex with anyone cheating on me

As long as you're both agreeable, why not?

I think it's fine. Sex is a basic human need, not restricted to procreation or the fairy tale of marriage. Take it where you can get it. 🤷🏻‍♀

It depends on your relationship.

You're giving a bit of yourself to someone who doesn't value you. I say no. If they are cheating then they forfeit that right. Also, there's no family stability. Stability is based on trust and they broke that trust by cheating.

you don't have to stay with them .. as far as if it's ok to have sex with them what do you mean? against their will?

Women think differently than men ..if she's cheating use her for sex ...get your thrill ..if she hadn't cheated would have been making love now it's just sex ..open it fill it forget it

Not for me. It`s either me or you go off with that person.

I try to not judge people
