Be gentle. Be slow and linger. Let your lips touch gently. No crushing together or mashing. Just feel the feel of her lips. Maybe you might move your lips a little, almost like nibbling, but less so. Feel her nose. Even rub it with yours, as if you were a deer. Be patient. You are both learning together how to make each other feel good.
Lips are soft and it is a pleasure just touching them. Dryer is better, but a little moisture to facilitate sliding lips against each other is fine.
Later on—maybe many dates later, depending on how old you are, you might start including a little tongue. Just a little between your lips. Maybe run it along her lips very lightly. Maybe she will meet you with her tongue.
French kissing is pretty sexual. It’s for when you are pressing your bodies together full length, and you are both aroused and you can’t keep your hands off each other and you just need to be inside each other. Your tongues might probe inside the others mouth and they might swirl around each other—whatever seems necessary at the time.
When in doubt, though. Slow down. Too fast can turn off most women. But if they want more, they will let you know.
It’s not science. It’s people relating to each other and everyone is different and for some people this advice is useless. But try not to worry about it. It will come. You have a lot of time to learn. You won’t get it perfectly the first time, and maybe never. No big deal. The relationship is what is important. Focus on your relationship, and all the physical stuff will follow without too much thought.
