You could have a peak one day and not the next. It's a drive that you have. I remember being 13 and being panicked about kissing. I like the kiss where one of you puts a potato chip in your mouth and then the other tries to get to the potato chip. Then there is kissing someone all over their body.
Some people like to have their toes and fingers kissed.
Kissing the neck and the shoulders is very sexy. French kissing is also very sexy but those of you who are not ready for sex yet should stay away from this kiss. Then there is the Eskimo kiss, where you kiss with your noses. Your noses touch each other. Kissing someone on the head is also wonderful.
