Sexual intercourse activity and activities associated with sexual interaction in Norwegians of different sexual orientations and ages

To study different subgroups of Norwegians' frequency of sexual intercourse and the activities that Norwegians engage in during intercourse. Data were collected from a questionnaire survey of a representative web sample of 4,160 Norwegians aged 18 to 89 years. The response rate was 35%. The majority of men (65%) and women (61%) reported sexual intercourse activity during the past month, and it was most common to report such activity 2 or 3 times per month. Partnered participants most often reported having intercourse weekly. The intercourse frequency of 2 to 3 times per week declined from 35% in participants aged 18 to 29 years to 8% in participants 60 years and older. The most common heterosexual activities reported were vaginal sex, stimulated genitals with the hands or mouth, use of sex toys, and anal sex. Younger and middle-aged Lesbian, Gay, Bisexual, Transgender/Transsexual, Intersex, Asexual [LGBTIA] men most often reported activities such as mutual masturbation, oral sex, and anal sex. Younger and middle-aged LGBTIA women most frequently reported mutual masturbation, vaginal sex, and oral sex. There seems to be a generational shift in types of activities in participants 59 years or younger, and those 60 years and above.
