Polyamory Advice

Is anyone in here in a polyamorous relationship? My fiancé brought up the idea of polyamory today and I’m giving it some serious consideration. I’m bi and would be totally okay with bringing another woman into our relationship. I guess I’m just looking to hear from people who’ve done it. What’s your experience been like? Do you have any likes/dislikes?

*Update* I guess the appropriate term I was looking for was actually polyfidelitous because we’d all be in a relationship with each other.
