When I had just turned 21 I worked at a clothing store. A new girl started, Im fairly certain she was 15 at the time, however I did not know her date of birth. She was interested in me, and asked me for my email address, which I provided.
Over the next few weeks we got to know each other, went to movies, chatted online, had coffee. One day we met up came back to my apartment and she gave me oral s**. Shortly afterwards we separated, although we did continue to chat on the internet and did run into each other, although not in the past 10 years.

This was over 12 years ago, and we both got on with our lives. Im married with one child and another due very shortly. She got into vet studies and finished that.

I do feel somewhat bad about the fact that as a 21 year old I engaged in naughty behaviour with a 15 year old. No one ever complained about it though, and its unlikely that this will ever happen. When my son is the appropriate age I will share my memory with him and hope he does not make the same mistake his father did.
