Well, a person attracted to 11 year olds could be classified as a hebephile rather than a paedophile, depending on whether the child is pubescent or not.So you're saying an adult who touches up 11 year old boys is a sex offender but not necessarily a pedophile?
Turn it up. A pedo is someone who is attracted to children or someone who fiddles with kids. It's not the sort of thing that people experiment with - people do it because they're into it.
A person who steals something is not necessary a thief, and a person who smokes a cigarette is not necessarily a smoker - but it's not as if a child sex offender can say:
"I only touch up kids when I'm drinking so I'm not a pedo"
If you touch up kids you're a dirty noncy pedo.
Sex offences are not inherently linked to attraction.
There can be motivations of power, revenge (usually indirect, such as against a parent of the child) and self-gratification (it is often not the "adult who touches up young boys", but the "adult who gets young boys to touch him up" or a completely screwed up understanding of sexual development (the parent who tries to teach their child about sex in a "practical" manner).
The term is more popular as a pejorative one, often mistakenly employed (particularly in the media). It only serves to inflame emotions, rather than promote any sort of sensible discussion.
