Norwegian Data on Prevalence, Sexual Risk Behaviors, Sexual Problems, and Sexual Satisfaction in Men Who Have Sex Exclusively with Women, Men Who Have Sex Exclusively with Men, and Men Who Have Sex with Men and Women.

Objective: This study investigates how men who have sex exclusively with women (MSEW) differ from men who have sex exclusively with men (MSEM), and men who have sex with men and women (MSMW) on selected variables. Methods: A probability-based web sample of 2,181 men was recruited. Results: Most MSEM considered their sexual identity as gay, and most MSMW as heterosexual. The MSEM were the most frequent condom users, while MSMW were the least frequent users and had the highest number of sexual partners. The MSEM and MSMW had a lower likelihood of premature ejaculation than MSEW. Conclusions: MSMW should be targeted in health campaigns.
