Ive liked a girl for a little while now but she seems to be really shy and its really hard to talk to her. I finally asked her out and she said yes. I want to kiss her but its the first girlfriend Ive ever had and I don't want to mess it up by doing something wrong in a kiss, though I don't want to wait to long to kiss her and upset her. Please describe to the best of your ability on how I should go about kissing her.
