In the early s, a therapist named Robert Longo was treating adolescent boys who had committed sex offenses. Their offenses ranged from fondling girls a few years younger than they were to outright rape of young children. As part of their treatment, the boys had to keep journals — which Longo read — in which they detailed their sexual fantasies and logged how frequently they masturbated to those fantasies. I sexually offended against a year-old boy; I made him lick my penis three times. Sex-offender therapy for juveniles was a new field in the s, and Longo, like other therapists, was basing his practices on what he knew: the adult sex-offender-treatment models. Also, research over the past decade has shown that juveniles who commit sex offenses are in several ways very different from adult sex offenders.
