Attraction to adolescents. It really is significantly different from adults who enjoy terrorizing uncomprehending toddlers with their assaults. With an adolescent, the child may actually be enjoying it at the time, and in some cases may have initiated the "relationship" and/or eagerly seek to continue it. It rarely involves physical violence or threats by the adult. This makes it a lot easier for the adult to convince him/herself that it's all really consensual, and therefore okay. A guy who rapes 5 year old girls is very different from a male middle school teacher who has affairs with eager 12 or 13 year old students. Both wrong, but very different.
