well if you're really comfortable with your current relationship..maybe you could ask her for some pointers..make it into a game kinda. you teach her something, and she teaches you..it doesn't have to be embarassing that way. i must say i wasn't the best kisser to begin with, but you just get used to it and there's no right or wrong way to kiss..it just has to feel good for both parties. chemistry also helps out too..cos if you have no connection the kiss is most likely gonna suck.
