Does this make me a slut or something?

I've been really good friends with this guy for 2 years and I always secretly liked him. Well today he asked me out and all that stuff and we kissed like first 5 minutes of us being together lol. It wasn't my first kiss(if it was I would have waited at least a month like I did with my last bf) does it make me a slut or anything just cause we kissed that early in the relationship? Btw I'm 15.
