confused?

so I'm 14 (pretty young) but most of the girls in my grade have done something sexual, and they boys are asking girls to do stuff and whatnot. I like kissing and all of that, and i have thought about doing stuff but when it comes to the time to do it i just cant bring myself to doing it it grosses me out and it seems impossible. maybe I'm asexual? but I dont think I am because I am attracted to people and I think about making out/being with someone. but ah idk? should I not think about it because I'm so young?
