Hypersexual Desire in Males: Are Males
With Paraphilias Different From Males
With Paraphilia-Related Disorders?
Martin P. Kafka
and John Hennen
The assessment of current sexual behavior (fantasies, urges, and activities) and
sexual preoccupation (measured in min/day) associated with both conventional
(i.e., adult relationship-associated) or unconventional (paraphilia and paraphilia-
related) sexual behavior were ascertained from a sample of 120 consecutively
evaluated males with paraphilias (PA; n = 88, including sex offender paraphil-
iacs; n = 60) and paraphilia-related disorders (PRD; n = 32). In addition, an
assessment of hypersexual desire, deﬁned as the highest sustained period (at least
6 months minimum duration) of persistently enacted sexual behavior (total sexual
outlet/week [TSO] after age 15) was assessed. In almost all measures, the PA and
PRD groups were not statistically signiﬁcantly different. The average PA or PRD
reported a mean hypersexual TSO of 11.7 ± 7.3, a mean age of 21.6 ± 7.1 years at
onset of peak hypersexual behavior, and a mean duration of 6.2 ± 7.6 years of hy-
persexual TSO. When the sample was stratiﬁed into three subgroups on the basis of
the lifetime number of PAs+PRDs as a proxy measure of the severity of sexual im-
pulsivity, the “high” group, with at least 5 lifetime PAs and PRDs, consisted of all
paraphilic males, predominantly sex offenders, who self-reported the highest hy-
persexual desire (14.3 ± 7.9), the highest current TSO/week (9.9 ± 8.1), the most
current sexual preoccupation (2–4 hr/day), andthe highest likelihood of incarcera-
tion secondary to paraphilic sex-offending behavior. Although hypersexual desire,
a quantitative measure of enacted sexual behaviors, may be a meaningful construct
for clinically derived samples, the incidence and prevalence of hypersexual desire
