No, it didn't happen today.
I still have the diary I kept when I was 13. One entry says, "First kiss, can't sleep." It happened at my eighth-grade graduation. At the end of the evening, Richie, my best friend Algene's boyfriend, kissed me on the cheeck.
How was that a first kiss? I can think of a lot of scenarios for a first kiss, but someone else's boyfriend's lips grazing my cheek is not one of them. Still, at the time I thought it was. And I couldn't sleep. I guess it doesn't take much to make an impression on a 13-year-old.
When did I get my first real kiss? The kind that a Kevin Costner character described as "long...slow...deep...wet"? I have no idea. No memory of it whatsoever. I guess by that time I was old and jaded and no longer impressionable. Maybe 14.
