Sexuality confusion

I have only ever slept with and dated men, and I have always found I am definitely attracted to them, but I don’t feel any romantic or emotional connection. I also mostly masturbate thinking about men, and even when I do fantasise about women I usually flip to imaging a guy as I orgasm. My fav porn genre is also gay male porn. I also always notice attractive men on the street and I don’t notice women at all in the same way, and could not imagine going on a date with a woman who I had met on a dating app or something but have with many men.
BUT I have only ever romantically fantasised about women (thinking about wanting to cuddle and be close to them) and have almost exclusively crushed on women and really intensely (particularly my close girl friends I have a steady stream of best friend crushes). Even though I think about men sexually way more than women I don’t know if I have ever had a crush on a man. I definitely am physically attracted to the women I crush on but only those specific people, whereas I feel I would be sexually attracted to a bigger range of men. No-one knows how I feel towards women since I have always presented myself as straight and I wouldn’t feel comfortable disclosing it either (also would not want my friends to guess how I truly feel towards them because that’s awkward). Would love some input, or if anyone has experienced similar sexual confusion?
