I wanna sleep with other men so bad

Just because you are in a relationship that doesn’t mean you stop being attracted to other people. If you have been in the relationship for a while then try spicing things up.

WELL...... you seem Poly, and that is normal and right for humans to be, even if you feel MONO is right, you literally built to be POLY!

If you're feeling like you want to experience that then perhaps you should end your relationship.
