Am I asexual?

So, I'm female and 14. I've been wondering for a while if im asexual, aromantic, boath or neither. To start off, I've never had a crush, I think dicks and vaginas are gross and so is sex. I have never been able to tell if someones supposed to be "hot" ive just never seen it. Kissing is also gross.

I've allways been open about not having crushes to my friends and family. I researched asexuality and people being aromantic and I thought "yea, I think that might be me" so today I told my friends that I think I'm asexual the response was pretty much "you shouldn't say that until your 18" and "you shouldnt say that"

I just want some help figuring it out.
