Objectives: Data on non-consensual sexual preferences (voyeurism, exhibitionism, toucherism and frotteurism, stranger rape, sexual murder) are scarce and are largely drawn from forensic samples. This may motivate premature and even false conclusions about the nature of these preferences (e.g. that they are intimately connected to psychopathy and/or general criminal tendencies, low intelligence or social pathology). There is also not a universal agreement, whether preference for non-consensual sexual activities (NC) and sadism (S) are independent or interconnected. To fill in this knowledge gap, we carried out a population based representative survey, in the Czech Republic, Europe, in 2016.

Materials and methods: We developed a questionnaire containing 124 items, including 5 and 2 blocks of questions, aimed at NC and S preferences, respectively. The questionnaire was administered online by sociodemoscopic agency, using quota sampling method representative of the last national census. The non-consensual subsample was defined as males who indicated either strong or full preference (number 4 or 5 on 5 point numeric scale) to at least one of the NC activities: voyeurism, toucherism and frotteurism, exhibitionism, stranger rape, sexual manipulation with the unmoving body. SM preferences were analysed separately. Descriptive statistics and factor analysis was used for data reduction.

Results: The final sample included 5023 males. The NC subsample comprised of 1252 males, i.e. 24.9% out of the main sample. Prevalences of NC preferences in the main sample were as follows: voyeurism (16.6%), toucherism and frotteurism (12.7%), manipulation with an unmoving body (5%), exhibitionism (3%), and a preference for stranger rape (1.7%). There was a high proportion of co-morbidity of these preferences: the more serious the act, the more likely it was accompanied by preferences for less serious NC activities. Importantly, men who scored high on S preferences did not prefer NC and vice versa.

Conclusions: In a representative sample of Czech males, we observed quite large prevalences of preferences of NC activities. The fact, that preferences for various NC tended to co-occur points to the possibility of a common underlying cause, which is consistent with the “courtship disorder” theory by Freund and Blanchard (1986). NC and S preferences did not group together, which could mean that they are aetiologically different. This conclusion is congruent with recent findings by Harris et al. (2012), Seto et al.(2012) and older findings by Kolarsky and Madlafousek (1972). Implications for further research and therapy will be discussed.
