I have very recently started dating a couple after deciding to explore the ENM space. They are both such wonderful, kind, sexy people. I have had three way dynamics before but only ever as a one off and never with a pre-established couple.

I have a stronger connection with the guy because we have a lot in common and have talked a lot, and she is super beautiful and laid back, if maybe a little shy.

He seems to want the relationship to move faster than I'm comfortable with, he also has told me that they have no boundaries (which is maybe a bit of a red flag). I have never been great at setting boundaries with people but sometimes the speed in which it's moving feels so overwhelming and intense, even though I really like them both. I'm also slightly worried about the social stigma of this dynamic.

I'm doing a lot of research into this but most of the information I can find is for/about the people in the original couple, any advice is greatly appreciated.
