Friends with benefits..

okayyy so this guy that went to my school hit me up on snapchat and wanted to hang out so i’m like “okay he’s cute let’s gooo” so we just walked on trails and shit all day and i explained to him how i’ve never done ANYTHING besides a few quick kisses. no relationship ever. and later on he kisses me. so anywayyyy i straight up asked him on snap what he wanted and he says he wants to be friends with benefits.. like i said i’ve only ever kissed two, now three people in my life and never dated anyone. so wtf do i do? i’m attracted to him but i get really nervous and shy especially after he kissed me, which i pulled away from after 5 seconds lol.. so wtf do i do?? any advice helps
