It seems to me that this superabundance of sex theories, which for the most part are mere hypotheses, and often quite arbitrary ones, stems from a personal need. It springs from the desire to justify one’s own abnormal or excessive sex life before bourgeois morality and to plead for tolerance towards oneself. [...] There is no room for it in the Party, among the class-conscious, fighting proletariat.

I was also told that sex problems are a favorite subject in your youth organizations too, and that there are hardly enough lecturers on this subject. This nonsense is especially dangerous and damaging to the youth movement. It can easily lead to sexual excesses, to overstimulation of sex life and to wasted health and strength of young people. [...] Young people are particularly in need of joy and strength. Healthy sports, such as gymnastics, swimming, hiking, physical exercises of every description and a wide range of intellectual interests is what they need, as well as learning, study and research, and as far as possible collectively. This will be far more useful to young people than endless lectures and discussions on sex problems and the so-called living by one’s nature.
