I found a very good lesson in how to kiss on Retronaut. It's from 1942, and it tells you exactly how to perform this difficult, but oh so lovely, act!
Now you know, and all you really need to do is find someone willing to practice with you. Good luck!
To give you a few extra hints on how to behave, I will also show you an excerpt from Always Ask A Man: Arlene Dahl's Key To Femininity from 1965.
