I'm new so I'm not sure if I'm posting this on the right sector of the website but I just really need other peoples insight on me and my sexuality.

Since a young age I've identified as bisexual but recently my friends have been telling me that they have troubles of seeing me as one. It doesn't help that there is no women that I'm attracted to currently.

Did I think I was bisexual purely because I grew up in an all girls school? Am I actually straight...?

I'm quite certain that I would like sexual relationships with girls but I have no real experience so I wouldn't be 100% sure.

Romantically speaking... I can't exactly picture myself with a woman, i can vaguely see myself being romantic with a man but if I'm honest, I don't think I'm capable of romantic relationships.
I have liked(?) girls before, but even if I have wanted to pursue them, I can't tell the difference between platonic and romantic. I was also younger then, for context I was a pretty emo child so looking back, was I just desperate for connections and I've just mistaken it as intimate?

This is all pretty idiotic, usually people stress about not being heterosexual yet here I am...
I want to assure anyone reading that I am not trying to be offensive or anything, I had some deep (?) crushes in my primary school so I rolled with it and identified as bisexual. I've 'been'(?) bisexual for so long it comes as a shock that I might be anything different.

Thanks for reading all this, it's actually really nice to talk about this whole situation as I mostly feel extremely insensitive when I do haha... <3
