Going to the dock at night with a couple of guys...help?

I wouldn't dress up. He's gonna hug you and feel free to hug back! but I am veryyy happy to see youre not going to drink cause im almost 17 and have the same mindset. If things get too uncomfortable (which they most likely will) dont hesitate to leave or tell them to back off or behave or something. This kinda sounds like a hook up? If you start to like him, then dont feel bad if he kisses you but trust me, he will move fast and try more. dont let it get too far. It sounds like fun though!
