I remeber mine well. It was with a girl on a student ambassador trip in 2006. We were staying in a college campus in Wales and there were a few us sitting around and the question suddenly came up of whether I had kissed a girl or not. I answered "No." The girl who asked this question then popped out of her chair, walked right up to me, and gave me a quick five second French kiss. It was sudden and unexpected, but I won't forget it.
