I wonder if you might find reading something like “For Men Only” and “For Women Only” helpful. They’re both books explaining some of the differences between men and women and the way their brains work.
Someone in a support group I go to recommend reading “For Men Only”, which is about women. I ended up reading about half of “For Women Only” as well. As a guy, it was helpful to see how despite being not very traditional a lot of my concerns/insecurities were pretty normal for men.
Most of my interests early on were nerd things like sci fi, video games, etc. I guess I was always drawn to music and drawing and those sorts of things, too. I did play a lot of sports with friends growing up but never in a team.
I didn’t realize how much I enjoy being competitive until later on when someone pointed it out to me. I got into sports more after that. Part enjoying it as entertainment and part motivation for getting out and having fun or getting more exercise. Partially to burn off all the pizza I shoved in my face on Sunday watching the NFL.
