1. Married couples have a lot of sex (reality: 56 times a year on average)
2. “Real men" are ready for sex most of the time with rock hard sustainable erections (reality: in a survey of men between the ages 40 and 70 years, 52% reported some degree of erectile difficulty)
3. “Real men" always cared about women’s satisfaction (reality: As long as sex was considered primarily as the means of reproduction, pleasure was left out of the equation of female sexuality, particularly in the male-dominated societies in the west. This began to change around the 1960s. The mass availability of reliable contraceptives and women’s heightened awareness of their individuality have rendered procreation a markedly lower priority and simultaneously dampened the double standard in regard to sexual fulfillment)
4. A sexual intercourse is prolonged, vigorous and consuming (reality: in the middle of 20th century 75% of men ejaculated within 2 minutes . The duration of intercourse did not become a major clinical issue until the past 2 decades or so)
5. Most of women have an orgasm during a sexual intercourse (reality: 30 to 40% of women do not have an orgasm with intercourse)
6. Although the majority of people do not believe now that a sexual intercourse should be used for reproduction purposes only, for many, the perception of what constitutes desirable sex is shaped by images in the media, in which nonverbal genital sex is often overvalued (reality: since the reality of pp. 2 - 5 there is a strong need for manual, oral or self stimulation).
