I'm not sure if I like this dude or not

Me - 15, girl, never dated, virgin, low self-esteem. idk any celebs or pop song or whatever, the only thing i know bout is anime, japan and sex in mangas.
so, ive never liked anyone and never been liked before, im a total newbie to this type of stuff. tho i do read a lot of mangas so i sorta know(?) the basics. but still, magas and reality is different. and theres this dude, he's mt classmate and he watched anime too. we got closer in the past few months to the point that we talk bout sex & hentai like it's nothing and it's fun talking to him. so rn im not sure if i like him or not.
he did ask me to go to prom (which is still a loooooong time away) and go to the movies (once but we didnt go yet) so im not sure if he feels the same. and the thing is i always think to far ahead bout things like, what if we break up? what if i or him lose interest? how to sex? what if i make the wrong move? stuff like that.
Plus it's not smthing cute and romantic like 'ohhh I think of him 24/7' or 'my heart throbs when he' s around' or 'our eyes met twice a day'. No... just no stop, it's not like that. So I'm not sure if I'm mistaken ING my feeling as 'like' or 'friendship' since I never had a friend to talk bout a ime before.
so rn the problem is..... what shoud i do? i dont wanna just 'go for it' and it turns out that he only c me as a friend then our friendship gets awkward, i dont want that........
WTF AM I SUPPOSE TO DO!!!!???
