help!!

so i’ve been sexting this guy for a while, he’s a junior from my school and i’m a freshman. but basically he keeps asking me if i wanna hang, and i know it’s just to fuck. i’ve told him i’m a virgin and he’s been really sweet about it. but i’m super self conscious about certain things about my body, like my stomach is too big and i’m pretty hairy on my back and ass. i’m also really nervous it’s gonna hurt. what should i do?
