I really need relationship advice!

Okay so I’m almost 16 and I’ve never had a real relationship. Like I’ve had boyfriends but nothing serious it was kid stuff. I’m really liking this guy. He’s sweet. I met his on snap chat he’s 17. He came to my house yesterday to meet me. He’s a little shy and he’s cuter in person. I want to get to know him and hangout and stuff but I’m sooooo shy. Like I can’t talk to order my food. I just want this to work out. How can I be myself? How can I stop being shy around him? Please help
