When did you 'figure out' your 'sexuality' or have you never really understood it?

I didn't discover sex until mid-20's, never had girlfriends in school or when I tried university after high school. Parents were divorced when I was 12, neither of them ever talked to me or tried to help me navigate 'discovering' what sex and sexual attraction meant or was. I've never been big on friends in general, and throughout most of my childhood I always did things by myself.

I've always felt very confused about sexuality and sexual preferences, and don't feel I've ever really understood where I stand/sit/walk in that space.

Anecdotally, a lot of people seem that they 'worked it out' early on in teenage years, or they 'knew instinctively' what their sexuality and sexual preferences were by the time they became adults. I can't say that's happened for me.

I suppose for me because I doubt myself so much in terms of social anxiety and have a massive fear of everything around sexual attraction, sex, intimacy, relationships, etc. I find sexuality, etc. to be a 'blocked out' topic area in my mental 'library'.

Being single long term in a 'couples world' (as manufactured 1st-world cultures tend to be) kinda makes you question everything about your understanding of human intimate/sexual interactions because everything focuses on being 'coupled' and as a single person you're socially an outlier.

I'd love to get other people's perspectives on all this as I know we're all different.
