have fun and definitely enjoy your prom. It's one of those experiences in life you shouldn't skip.
Honestly it won't be "the most magical night of your life" but you'll probably have a lot of fun and get laid.
Oh and be safe.
My prom story: I had a GF at the time who was short and kinda bitchy. One of my really good female friends was going to the prom stag so I told my gf, "
look we're not going to last forever obviously, so I want to go to prom with a friend not a girlfriend" It was harsh but necessary. Made prom a hell of a lot more fun and the after party kicked ass. Needless to say though I didn't get laid that night and she broke up with me a couple days after that but yeah. Totally worth it.
