Dating Advice

So I'm on the brink of going on more dates with this guy. I'm 17 and he's 20. He has had relationships before, but I haven't and I've never even had my first kiss.We both really like each other and talk a lot, and have plans on going out and all of that. I know that things will become official, whether I make the first move or not, but I'm just nervous because I've never been in a relationship AND I'm not out to my parents.I would love to hear people's advice of there first relationships and just things I should really know in general. I'm in my head that things would go wrong real quick, but I really like him and he seemingly likes me back.So yeah if you have any advice, let me know! Thanks!
