Objective
To assess the frequency and associations of barrier protection use during sexual activity in a population of women who have sex with women (WSW).Methods
WSW were invited to participate in an international internet-based survey. Information regarding ethnodemographics, sexual health, and barrier use during sexual activities was collected.Results
The study cohort comprised 1557 participants. Barrier use was least prevalent during digital genital stimulation (11.3% ever used barriers) and most prevalent during stimulation with a sex toy (34.4% ever used barriers). Univariate analysis revealed that women in non-monogamous relationships were more likely than monogamous women to always use barrier protection for sexual activity (14.3% vs 3.5%). On multivariate analysis, there was no association between barrier use and frequency of casual sexual activity or history of sexually transmitted infection. Small associations were noted between barrier use and certain sexual activities, age, race, and number of partners.Conclusion
Many WSW do not use barrier protection during sexual activity, even in the context of potentially risky sexual behaviors. Safer-sex practices among WSW merit increased attention from healthcare providers and public health researchers.
