Hello Blue Dragonfly,
Welcome to our forum.
You'll probably need many talks with your husband, and lots of empathy for his feelings, during this poly journey that you are on. He may be hard-wired to be monogamous himself, but there's still a chance he'd be okay with you having multiple partners. He'll probably need a lot of reassurance, though.
It certainly is a strange world, where many of us ended up trying to "force ourselves to be monogamous," but I think monogamy is okay for some people. I hope you'll enjoy your time on Polyamory.com, and get to know many of us better (as we get to know you).
Pleased to meet you here.
Love means never having to say, "Put down that meat cleaver!"
