You're getting waaay too ahead of yourself here! We're talking about going out, not kissing just yet!
Kissing is 'on the job' training, it comes from a very special part of yourself, it's very emotional and based on how you feel about the other person. It's not so much about prior experience! So, there's this unknown part of yourself waiting to be discovered. When the time is right, and the feelings are there, you (and she!) might discover a real, hidden talent.
Don't worry about it, you'll be fine. Just wait until the feelings are there and lead with your heart.
