Should I hook up with him?

I'm thirteen and I have a boyfriend-if your answer is: Your too young!!! then just x out of this page. So anyways we were like about 2 kiss at this one party but we didn't and today his best friend fb chatted me & said: would u hu (hook up) with John @ Lea's bat mitzvah? I told him it was none of his business but I was going to plan to, but now should I not just to punish him for talking about it with his friends, or let it go?
