Flickr photo by davidChiefKissing on the first date ... for me, it's a no-brainer. Unless I'm just not interested in the guy, I see no reason not to.
But not everyone is like that. I have a few friends who have a very strict "no kissing on the first date" policy.
I'll admit, sometimes it can be worth the wait, which is why I think those gals hold off. It lets the passion and excitement build up just that much more. Unfortunately, I'm a pretty impatient and impulsive person, and I hate being in that awkward kiss/not to kiss limbo after he's walked me to my front door, so I usually just go for it.
What about you? Are you usually open to kissing on the first date or do you like to wait?
