Kissing is one of the absolute greatest pleasures in life. Like anything that’s worth doing, it’s worth doing well. Practice makes perfect, and you can’t practice kissing by yourself.
Being relaxed with the girl and the situation is the first step to a great kiss. Your girl — even a new girl — can imagine herself in your arms kissing you or she wouldn’t want to date you. So calm down. She likes you!
The second key to better kissing is to start slowly. This gives you both a chance to “feel” your way into a comfortable lip lock. You will guide each other (or you can let her guide you, if you have no confidence or experience with kissing.)
Get your lips close to hers and just brush them gently together, barely touching, and see what happens next. Don’t forget to close your eyes. Just mirror what she is doing. Be gentle and playful. Follow the action and let your instincts take over.
Constructive criticism may be helpful, too. All the advice in the world won’t be of any use if it doesn’t please the lady you’re with. Ask her what she would like. Then take her advice and practice, practice, practice.
