first date

So last night I was snap chatting my crush (I'm 14) and we've never talked in person but we sc all the time and we decided to go on a date next week to the movies!!! My parents don't know and I don't know how to tell them because I've never talked to them about boys before. Is there any advice you have about the date or my parents? I've also never been on a date before or even had my first kiss but I'm ready.
