My first kiss was actually on my hand, he was a kid obsessed with break-dancing who lived next door to me, I was 6 years old.
He asked to kiss me on the mouth I said no, then he asked to kiss me on the cheek and I again said no, then he asked to kiss my hand and I said yes. Then rode my bike home as fast as I could. He was older than me, I can't remember how old though.
