In 88 female prostitutes 18-29 years old we examined main characteristics of their private sexual activities. The results were statistically compared with the results of a control group including 173 women of the same age from the representative national survey of sexual behavior of Czechs. In the group of prostitutes signifi cantly lower age of the fi rst intercourse was found (mean 15.7 years), three times higher number of sexual partners, more casual sexual contacts. They masturbate more the twice more than the controls. In the private sexual life prostitutes are more concentrated on the satisfaction of their male partners – they state more frequently fellatio and masturbation of the partner. Compared with controls they also have more abortions, STDs and sexual dysfunctions. Half of the sample state homosexual experiences compared with 7 % of the controls.
