What sort of challenges have you encountered in polyamorous relationships (as opposed to more traditional ones)?
Sharing my love and attention to both partners has been a challenge for the most part. I never want my partners to feel excluded, but to have the same attention and love they deserve. I don't want to give too much of it to one partner and make the other feel neglected or worse, abandoned. It's very important to find a balance, and I'm still working on that, it's a progress. Communication is a major key in this, I always discuss these things often with both partners among other things. I'm extremely open about these things.
Then there is jealousy, and both of my partners have felt it, and I address their concerns when they feel that way. You can't really tell someone to get over it, jealousy is completely normal, everyone feels it. So I try my best to give them what they need in those moments to help them overcome it.
It's progress, and has gotten much better over time in the last 9 months or so.
