Am I bicurious if I find some girls really beautiful but can’t imagine myself doing anything sexual with them other than maybe kissing if even that?

it all depends on what you personally define as bi curious. if you find someone beautiful but can't imagine you doing anything sexual with them then it is likely that you are bi romantically curious, people often think that being bisexual is one thing when really it is a spectrum and there's no two people that are at exactly the same point on the spectrum no matter how close they seem. people often think of being part of the LGBT community is a specific type of person and it's not it's all about how you feel about yourself and not what others think of you.

Appreciating aesthetic beauty doesn't equal feeling sexual attraction: anyone can appreciate people's beauty, even if they wouldn't want to have sex with them. So if you are attracted to men, and see women's beauty but aren't attracted to them sexually, you are straight.
