There has been a lot of research conducted on pedophilia. Google scholar illustrates the volume. Based on what I read:
1. Pedophiles are almost always male – theories suggest it has something to do with the Y chromosome and other male traits.
2. Not everyone who assaults children is a pedophile – the ‘true’ definition of a pedophile is one who becomes sexually aroused by pre-pubescent children.
3. Not all pedophiles molest children.
4. Some researchers suggest that some causes could be traced to en-utero and be the result of environmental factors such as alcohol, drugs, smoking, lead, etc.
5. Although some suggest that pedophiles are more likely to have been sexually molested themselves as children, when controlled tests were conducted, this became much less significant as a factor. In other words, a lot of pedophiles – once caught – blame shift.
6. Some research suggests that other factors, such as early childhood brain trauma, low IQ, etc. may contribute.
7. “True’ pedophiles become sexually aroused by images of pre-pubescent children, just as most hetero males become sexually aroused by fully formed females .(I’m extremely shallow – without boobs (Big) and a great ass and waist to hip ratio I’m not interested). Regardless of the root cause of a pedophile’s lust, experts indicate that they can’t change this any more than a ‘true’ hetero can change their desires. This is the reason why convicted pedophiles have their names, faces and addresses listed on websites in the US. So one could state that the ‘minimum’ sentence for a convicted pedophile is the rest of their life.
