Welcome to our forum.
Heh, you are truly veterans compared to me; I've only been in a poly relationship since 2006. I guess we're all newbies in polyamory, one way or another.
Anyway, I'm sure you'll be able to benefit many people here, and receive benefit as well. It's a wonderfully thriving community.
You sound like you have a beautiful triad relationship, and I'm glad for you. I'm also envious that you've been able to come out, and get such positive reactions!
It makes me feel more hopeful about things in general.
Glad you could join us, and pleased to meet you as well.
