Hi hat, I'm sorry you've found yourself joining us on the forum but well done for reaching out.

There are several reasons why people offend in the way they do with a sexual interest in children being just one of them. The courses which I think people may be referring to are courses aimed to help your son identify his triggers for offending and learning how he can address these triggers in a more healthy way.

My son did both the LFF course and CBT through a private therapist and found both to be life changing. With the help of the course he was able to identify his triggers e.g chronic low self esteem and work on improving this by putting things in place to help him make better choices and prevent reoffending. If you haven't come across it, you might want to have a look at the Good Lives Model. https://www.goodlivesmodel.com/information.shtml#General

If your son hasn't yet contacted the stop it now helpline I recommend that as a starting point.
