Should i stop seeing this guy?

Okay I'm almost 17 and he's 20 we really didn't know about eachothers age untill we talked on the phone. We met at each others work and he asked me out. I'm only in this town for like two weeks more and he kinda knows that I don't want anything serious. So since my dad would freak out if he knew I snuck out to see him. I was hone about 4 hours. Well he's in college so he told me he partys, he smokes weed sometimes, and he's not a virgin. Well I don't drink don't smoke and I'm a virgin. He didn't have a problem with it. So we hung out and we went to a park we did a dare and if I lost I had to kiss him well we ended up making out. We made out in his car and he started grabbing my boobs and my crouch then he like sorta kissed ny nipple. Now I asked my friends about it because I felt he was taking it to far and only wanted sex my friends told me that that's what all guys want which is true but when I told them he smokes and partys I should stay away. I truelly know I should stay away from him but I loved the way he kissed me and the way he held my hand. But that was the first time I ever kissed anyone let alone makeout. What should I do?
