Your boyfriend kissed another girl on a dare what do you do and is it a real kiss as in first kiss?

He obviously doesn't care much about you if he is kissing other girls or playing "dare" for that matter. Kisses aren't something you pass out to other people like that and "dare" is a game for people uninvolved and wanting some type of action.

(reply) Good point but his dare was from his friend and he really hates this girl, to be honest he cried because he was so upset, he didnt want to be called a baby also.

If his friends can influence him that much I would be very worried because it's obvious that he's dealing with peer pressure. He should be able to stand up to his friends and say NO and not care what they think of him after because by kissing another girl(and I don't care if he hates her) he went against your relationship.
