The Mail also has a story today about another teacher who regularly had sex with a pupil (aged 16) in a car park over several months. That teacher is a woman though. Do you think she will get the same sentence?
The term ephebophilia means " Ephebophilia strictly denotes the preference for mid-to-late adolescent sexual partners, not the mere presence of some level of sexual attraction" and I think that may be the phrase various posters are looking for.
However, we only have one sample here, so we can't say if he has a preference. I had a fling with an 18 year old when I was 30. I also had a lovely time at a gig with a 14 year old when I was 22. That doesn't make me a ephebophiole though - I just found them attractive (and I thought the latter was 18) I've also had partners older than me (when I was 17 and when I was 31) and both long term partners have been about the same age as me.
The point is that I expect a lot of us can point to individual relationships with people younger than us, but it doesn't mean we have a preference for them. JF may do, but none of us who don't know him can say for certain. What he did was immoral and also illegal, we do know that.
There is definitely no evidence that he is a paedophile though, and like the OP I was annoyed at the prosecution misusing the term.
