Did anyone know or have an idea that you were LGBT+ before you did?

When I was 23, I was dating a young lady who asked me if I was gay (which surprised me because we had a sexual relationship). She broke off with me a short time later.
A few months after that, I had sex with another man for the first time....she was the first one I told, and she told me she wasn’t surprised (even though I was surprised when it happened).

My parents said they assumed from a very young age that I was "different" in that regard. Not sure if they knew that I was bisexual, but they certainly knew I was not going to be a normal straight boy.

One of my buddies from school,said it in passing when I was but a nipper about 12/14 yrs old,

I think everyone did cause everyone would call me gay 🙄 even though I'm bi lol
