Kisses on the first date are great! Most of the time.
Here's a lovely story...
I went out with this guy and another couple. When we were watching a movie, he started surreptitiously picking a scab on his leg. He caught me watching him. Then, he had to get rid of it. So he shoved it in his shoe. Then he went in for the kiss. Needless to say, that kind of scarred me. I didn't kiss him, never went out with him again, and had to tell this story to all of my friends.
