I had a relationship of sorts when I was 15 with a high profile 27 year old. It didn't get as far as sexual but not for want of trying on his part. In fact that's why he dumped me. I lied about my age and he thought I was 19.
There was also a footballer called Adam something jailed for a similar thing. I think he thought the girl was 16+.
They weren't right but they weren't paedophilic.
