What does it mean when a guy ask for your number more than once?

Anonymous
I was inboxing this guy from my school I met at a football game and he kept asking me the same questions like "what did you do after the game?" I told him I just went home but he asked why me and my friends didn't go out and get drunk. Now he's asking me for my number...Ive only met him once and I'm not comfortable with giving people I don't know well my number What should I do? And does it seem like he only wants to talk to me as a hookup buddy?
