WHAT DO I DO?!?!

I've been single for about 4 years now - and the approach to dating for some reason is now a session of overthinking. No one knows I'm bisexual. No one. I dated girls ALL through high school, and one day I met a guy my age that I was drawn to. I don't know how to proceed. I've even thought about polyamourous relationships - or rather activities.

A few times I met gay guys, but we never really clicked. I'm not into guy sex, but foreplay and group for some reason made me feel like I found a place to be content. That happened twice. I also I met a trans guy who was the most beautiful girl I'd seen in some time, and looking at her put me beyond attraction. The things people said in the shadows about her made me angry. A week later, she moved away and I never found her again.

I am a painter and artist and where I am, everyone practically knows of me - even though my customers have different views (d-bag views) they pay the bills so again, I feel like I'm living a life that isn't mine. I thought maybe my proficiency at drawing human anatomy was what made me attracted to both sexes, but I'm not sure. I am completely lost. I'm also slightly scared. Avoiding connecting with people is starting to have bad effects.

Please, any advice you can give me would be so cool.
