Changes in sex differences in sexual behavior: A replication of a study on West German students (1966–1981)

In 1966, at the start of the student movement and the sexual liberalization process, we studied the sexual behavior and attitudes of 3,666 male and female students from 12 West German universities by mailed questionnaires. In 1981 we replicated this study with 1,922 students from 13 universities (10 the same as 1966, 3 founded after 1966). In both studies the students were selected at random. Results of these comparative studies are presented with a view to the changes in sex differences. Sex differences in masturbation behavior have considerably decreased since 1966; masturbation is nonetheless still the form of sexual behavior with the most striking differences between the sexes. The sex differences in coital behavior are now reversed, female students being earlier and more active than males. As regards the tendency to change partners or for sexual relations outside a steady relationship, the differences between men and women have disappeared. In their attitudes to sexuality, female students in 1981 are somewhat more liberal than their male counterparts, whereas hardly any difference could be found in 1966. These changes in sex differences are observed in all subsamples, i.e., in young and old, in strictly religious and nonreligious students, and in students from both upper- and lower-class backgrounds (educational level of parents).Revised version of a paper read at the 8th Annual Meeting, International Academy of Sex Research, August 22–26, 1982, in Copenhagen.
