I've been poly briefly, it didn't work out very well but it was probably because my main relationship was rocky to begin with. But I've always been in an open relationship partially out of being practical (my ex lost alot of sexual function after literal brain surgery), and because I really have never had feelings of jealousy when ive been with someone, it just doesn't register with me. I'm not possessive of my partners as long as we ask before either of us go out to fool around with other people. And I don't do random hook ups anymore. I have a core group of male and even a few female friends that I will meet up with to hang for a weekend and fool around. We aren't lovers, were all really good friends who share mutual kicks and kinks. But I hang out and mainly have my personal and sexual relationships in a very niche community. I will say that
I scratch my head when I see older guys like me who've been sexually abused and they freak out so hard because they have been married and have kids and realize they might not be straight and 1. think its because they were abused and it imprinted on them (i wont dismiss that this isnt a possibility but I strongly suspect it isnt the case) , 2. that if they inform their partner they also might have attraction to other men that their entire life will come crashing down. My brother in christ, if you love your wife and she really loves you, she wont leave you if you admit to thinking about other men sometimes. And I get it too, people in my younger age group have basically grown up in a MUCH more accepting environment for queer people than older folks have. Toxic masculinity is strong for older men, anything that even deviates from that slightly is a direct attack on them, and I bet its distressful.
Figuring out my own sexuality and coming to terms with how my abuse affected its development is really the ONLY thing ive managed to do successfully when dealing with all this shit and its probably why I've ended up having casual relationships with my best friends. But im really ok with that.
