Polyamory myths I see again and again 1. Poly means you're less committed to your partner 2. Poly relationships don't last as long 3. If you're poly you must like casual sex/have a higher sex drive/are promiscuous 4. If you're poly you must be with more than one person
I've been poly for nearly ten years now and it differs with each relationship - but overall it gets easier. Jealousy for me is primal 'fear that they'll steal my partner away' - but after years of my partners *not* getting stolen away, the fear is just less convincing.
