Norwegian Data on Prevalence, Sexual Risk Behaviors, Sexual Problems, and Sexual Satisfaction in women who have sex exclusively with women, women who have sex exclusively with men, and women who have sex with men and women.

The study explores the difference between Women Who Have Sex Exclusively with Men (WSEM), Women Who Have Sex Exclusively with Women (WSEW), and Women Who Have Sex with Women and Men (WSWM). The data were obtained from a survey of a probability-based web sample of 1,967 Norwegian women. Most WSWM identified themselves as heterosexuals (76.3%), and three out of ten used a condom when having sex with a new partner. The highest number of sex partners during the last year was reported by WSWM. More WSEW than the other categories reported premature orgasm. WSWM should be targeted in health campaigns.
