Anyone here in a poly relationship?

I am a bi man in a loving closed throuple (we dont go outside are bedroom) with a married couple. We all live together and share the same bed and life. We are family. The man is bi and is my boyfriend, she is my girlfriend. We all are sexually active together and with each partner seperately. 7 months into the relationship I started to experience ED and have been struggling for a year since then. Just curious if anyone here is in a non traditional family dynamic. I openly talk to them and have had therapy but still struggling.
