Hey, also don't kiss girls who aren't your significant other, or who are sending mixed signals. It gets awkward, especially if you don't know how she feels about you, or you don't know if she's single. Other than that, only kiss someone if you mean it, don't do it if it's a dare, or if you aren't happy in your relationship. Kisses are an intimate thing for people you love, not people you think you love.
Eh, sounds romantic but I wouldn't like being kissed if I'm arguing and not when I'm crying, unless I want it. Sort of feels like they're just shutting me up but I get the idea, kisses are nice but only when the other also wants it.
(edit: gets downvoted cause y'all jealous, admit it)
