idk what to expect in my first date

i posted this on another subreddit but i didn’t really get any responses so im gonna try here :)

hi! this is one of my first posts so i don’t really know what to expect, but basically i’m going on a first date today with this guy i’ve been talking to for a couple weeks and this is my first date so im kinda nervous. he’s 17 and im 15, we’ve talked in person and stuff but we’ve mostly called, but i am kinda awkward and don’t know what to talk about most the time. we are going to the movies and a couple of my friends are coming along but he was telling me he only wants to hangout with me the entire time (the movie is 2 and a half hours) so im very very nervous. also he has been very flirty and saying things like how he likes physical touch and how he would want to hold hands. physical touch kinda cringes me out but i really like him so idk what to do!! any advice would really really help!
