There is nothing wrong with kissing. This is not an anti-kissing thread. Kissing, like anything else in life, can be a wonderful experience. Believe me, my very first kiss was, at the time, a wonderful experience.
The fact is, however, all of these "when was your first time" or "have you done this yet" questions create imaginary social statuses for us to fall into. My having kissed a girl didn't make me a better man, it didn't solve my life problems, and it certainly didn't improve my romance life. Kissing someone won't automatically lead to marriage and it won't even lead to a decent relationship or an improved love life. It is simply an experience, and - like all experiences - is secondary to the more important factors they are part of.
Again, we are not condemning the act, by the over-hype surrounding the act. There are so many people dwelling on things like "I haven't (had sex/kissed a person/hugged a lobster) yet" when they should be looking to other things. The greatest thing that happened to me was when Christ raised me from my death in sin, not when I first kissed a girl.
