First of all if you like the boy you should wait, when you're alone or don't take it to fast.
If you don't like the boy and he's trying to kiss you get body guards and run away or make a contract to say do not come close to me within ten feet. If you're in the same class tell him back off and tell the teacher(act like you're telling the teacher. I have the same problem and my birthday was yesterday.
Or, if you are comftorable with kissing at your age and are comftorable with the boy, go ahead and kiss him back. Otherwise, if you are being pressured or feel like you have to do somehting fast, punch him in the nuts.
There could be more than one motivation behind his actions so it's best for you to think about his most likely reason for doing it and going from there. He could just genuinely like you and expressed his affection for you in an extremely bold way, in which case you can tell him you also have feelings for him. There are other possible reasons, however. For example, after you reach a certain age, little kisses on the lips mean almost nothing. It could have been a dare, for all you know. If you really can't figure out why he kissed you, just ask him. It may seem awkward but be casual about it and try not to make the situation more uncomfortable than it already is. I believe depending on his reasoning behind it, you should be able to figure out what to do on your own. Good luck!
Tell him to stop or kiss him back.
You should ignore him.
If you don't want him to kiss you then tell him "I don't want you to kiss me". If you like him but are not ready say "I am not ready". If you like him and you are ready just kiss him back.
If he kisses you for longer than a few seconds and tries to put his tongue in your mouth then he's trying to french kiss you.
When a girl tries to kiss your bellybutton, it is a way of showing affection.
Yes you can kiss a boy if you are a boy
slap him !
It means he loves you. He wants to kiss you.
You're not ready to be kissed yet. It's a subconscious thing.
It depends on how well you know the boy, and if you personally want to kiss him. If you don't want to, then lean away or turn your head so he kisses your cheek. If he is harassing you then ask him to stop and/or tell an adult depending on what he is doing and how serious it is. If you like him, then I say go for it, but it is up to you.
kiss him back and makeout
He might. What you mainly need to do is be concerned that you actually had to slap him to get him to stop. Please consult with a parent, teacher, guidance counselor, or such, especially if it does happen again.
