No! That's not a problem, in fact I'd say that's a good thing! 13 is WAY too young to be dating let alone kissing. Relax and take your time. You'll regret it if you do it too soon.
I have never been kissed at 13, is this a problem?
No its no problem
Not a problem at all. You want your first kiss to be special, so don't rush it, and kiss the right person who will make it special.
