You have no way of knowing if they (or any portion of them) are DOING anything wrong. I don't know if they are, but just acknowledging the attraction, doesn't guarantee they are criminals. Can I imagine what it might be like to fight that kind of attraction? Nope, but I do suggest there are gads of people that have odd sexual appetites that never act on them.
Would I feel comfortable with a person claiming to having it in check around me or my children? Nope, but that still doesn't make them criminals.
If we're not having fun, then why are we doing it?
