Am I asexual (read the text)

Okay sorry to bother you all but I’ve been really confused about myself I guess? This is slightly TMI but when I see a pic of a dude with barely anything on or nothing... I get grossed out and as a reflex I just quickly look away but when I see a naked girl I don’t get grossed out but I don’t really feel anything I just see her and think “okay you look pretty nice” but nothing over the top. So I feel like there’s no sexual attraction but then why do I have different reactions to dudes and chicks? I’m a girl and already identify as a lesbian (cause with relationships I already know that I don’t want to date a guy) but am I also asexual? I mean I’m 15 and It feels like everyone around me who’s my age feels sexual attraction but I don’t(?) or at least not as much as they do. Maybe I’m just so young that I don’t feel anything yet but later on will, I did start to start develop a little later then most people I know? But then again I’ve been like fully developed for a while now, so yeah I just really don’t know what I am. What do you guys think I am?
