The hypothesis that the preferential rape pattern belongs among the courtship disorders like voyeurism, exhibitionism, and toucheurism was tested. The study consisted of two experiments. The first compared 11 rape-prone males, who were most likely afflicted with the preferential rape pattern, with 11 sexually normal controls on penile response to narratives that depicted scenes in which the individual engaged in behavior typical of voyeurs, exhibitionists, or toucheurs. Narratives depicting normal tactile interaction (short of intercourse) with a genuinely participating woman, normal intercourse, and sexually neutral scenes were also presented. The rape-prone males responded more to the voyeuristic situations than did the controls. The standing of the normal intercourse situations on the scale of erotic value, relative to the other above-mentioned situations, was lower for the rape-prone males than for the normal controls. A second experiment compared 12 rape-prone males, who most likely demonstrated the preferential rape pattern, with 12 males with (other) courtship disorders and 12 sexually normal controls. Penile response to narratives depicting the individual involved in pretactile erotic activity, in tactile sexual activity short of intercourse, or in having intercourse was compared. Each situation was presented in two modalities depicting either a genuinely participating woman or a woman fearful of the individual. The penile responses of the rape-prone males, as well as those of males with other courtship disorders, differentiated less between sexual interaction with a fearful woman and such interaction with a participating woman than did the penile responses of normal controls. There was no significant difference in this respect between the rape-prone males and males with other courtship disorders.

In the context of a search for testable etiological theories of pedophilia, the relationship of pedophilia to partner sex preference was investigated. The proportional prevalences of gynephilia and androphilia were compared with the proportional prevalences of sexual offenders victimizing female children and of such offenders against male children. Since pedophilia either does not exist at all in women, or is extremely rare, only men were included in the study. We derived the proportional prevalence of androphilia from a review of the main pertinent studies, including Gebhard's reassessment of the study by Kinsey et al. particularly of the section on gynephilia vs. androphilia. The numbers of heterosexual vs. homosexual offenders against children were derived from the studies by Mohr et al., by Gebhard et al., and from a group of 457 sex offenders against children seen in the course of several years at the Department of Behavioural Sexology of the Clarke Institute of Psychiatry. There was a large difference between the proportion of prevalences of heterosexual vs. homosexual offenders against children on the one hand and the proportional prevalences of gynephilia vs. androphilia, on the other. This difference suggests that the development of erotically preferred partner sex and partner age are not independent of each other and that in pedophilia, the development of heterosexuality or homosexuality is brought about by factors different from those operative in the development of androphilia or gynephilia.
