[Sexual maturation in present-day trainees and students]. / Sexuální dospívání dnesních ucnic a studentek.

By means of a structured interview the author examined the sociosexual development of 303 single girls aged 16-18 years born in 1967-1970. 130 were apprentices and 173 secondary school students. Comparison revealed significant differences only in the group of 16-year-old ones. There the sexual development of apprentices was more rapid, they had more frequently sexual intercourse and more sexual partners. At the ages of 17 and 18 years the differences between the groups disappeared. These findings confirm the hypothesis that in this country the differences in sexual behaviour between different social groups are diminishing and disappearing.
