What would you do?

When at work I work with a variety of ages to 14 to 60 or even 70 year Olds. Well I work at hersheypark so there is this guy at my stand and he's 20 and I recently felt like he likes me and 16. We always joke around with each other but he loves to tease me, and tickle me. I caught him checking me out the other day but I didn't say anything because he's my friend and I don't see him as a pedophile because I know he isn't. He says sly comments like your cute or he commented on my butt saying I have a big ass. He even went as far as pinched my butt when I didn't move out of his way. What would you say about this? Is it wrong?

I'm on here all the time and I read about many people's age gap between them and their hubbies or boyfriends. So if he tried to pursue a relationship with me? Would you consider that wrong too?

P.s by the way he's an international so he will be going back to his home country in September
