How did you know you you were gay?

I need advice, as this realisation has hit me hard and I don't know who to turn to for advice as I'm considered by others as classically "feminine" but I work in a male dominated industry and can hold myself well against men. I've always found male attention repulsive and off putting. I have a lot of gay male friends but they seem to not like lesbians very much lol.

Some context: I come from a conservative background, I'm 32 and married young (to a cis male) and we are separated. I couldn't hide my lack of interest in being intimate with my ex and that I wasn't attracted to him, let alone males anymore.

I always knew I liked women but didn't process it as attraction. My first 'sexual' experience was when I was 8 with one of my good friends in my friendship group. We used to pair off together at sleep overs and make out. My first sex dream was when I was around 9 and it was of Kylie Minogue. Throughout my teenage years I had discreet crushes on friends, female teachers, female celebrities but just considered this as admiration of other females. I just don't seem to bond as well with men as I do women, even my ex. I don't know how else to describe this weird this feels for me right now, but how and when did you all know?
