My Husband Thinks He Was My First Kiss

The story I tell of my first kiss was when I was 14, with my now fiancee. False.

When I was 13, I babysat an 8 year old boy. His parents were very open, and he was very sexually aware (I caught him watching porn a couple of times). From the start, he was very agressive, always grabbing me and trying to kiss me. After a while, oddly impressed with this new sort of attention, and very curious about kissing, one night we started making out. This became routine, and went on for probably almost a year, before I realised how horrific and wrong my actions were. I continued to babysit him for a while, but soon his parents stopped calling me. I’ve always wondered why. I’m terrified that I’ll one day be exposed as a child molester.
