Out of a group of 700 Czech girls aged 16 to 18 years questioned by means of interviews 344 (49.1%) already had their first heterosexual coitus. Thirty-three of them reached orgasm during their first sexual intercourse and during second and further intercourses they were orgasmic mostly or always. The second subgroup comprised 32 girls who were anorgasmic not only during their first sexual intercourse but also during their further sexual life. Statistically significant differences between these two subgroups were found in the following items: Orgasmic girls were more frequently longing for their first sexual intercourse whereas of the anorgasmic girls the motives were curiosity or the effort to satisfy their partners. The majority of these girls experienced the first sexual intercourse as unpleasant and reported frequent occurrence of bleeding. Furthermore, they had to regret more frequently the loss of their fathers during the first 6 years of their lives than the girls of the first subgroup had.
