hes using me and i dunno what to do

hey. so the guy i’ve liked for around 3 years now is trying to use me and i dunno what to do. on snap we are eachothers number one best friend which means we snap a lot but before me and him started talking to each other 2 months ago his best friend added me and told me not to talk to him because he’s gonna use me and he only likes me for my body. and then a few weeks later he said “i know u like me and i dunno what ur intentions are but mine would only be sexual because i don’t wanna relationship with anyone. and i’m not trying to pressure u into anything if u don’t want to but i just thought we needed to talk about that” i would like to point out that he is 16 turning 17 and i’m 15 so like i havent done anything and i told him i wasn’t comfortable with that. (i still haven’t even had my first kiss yet because all boys wanna do is get in my pants and i don’t want that at all) i genuinely like this guy and don’t know how to get over him. do u think there’s a chance i could end up getting him to like me for a relationship (his best friend said he liked me for a few weeks and then stopped i dunno if that’s true or not) but i just don’t know what to do and i really like him and i need help.
