Cultural norms, beliefs, and values influence what is considered healthy sexuality. For example, homosexual intercourse is not only permitted but encouraged in some cultures. Yet, in the US it remained a "mental illness" in the DSM until 1980! "Nymphomania" refers to women in the Victorian era who were regularly orgasmic and enjoyed sex, and "masturbatory insanity" was a diagnosis until the 1930s: physicians believed that masturbation could cause fatigue, physical illness, and mental illness. These ideas persist today without scientific evidence to support them. For example, many varsity coaches insist that college players not have sex prior to a game because they believe it will reduce their athletic ability. What sexual disorders do you think are influenced today by our culture and how?
