The purpose of this study was to evaluate the acceptability, feasibility, and preliminary efficacy of using an online educational resource that presents research-informed strategies for women's pleasure, OMGyes. com, as a resource to empower women to broaden the ways in which they understand, advocate for, and enjoy sexual pleasure. A cohort of 870 adult women was given access to OMGyes.com and asked to explore the resource over a four-week period and complete online pre/post questionnaires. Participants reported a high level of satisfaction with the relatability, usefulness, and functionality of OMGyes.com. We observed statistically significant, large effect size increases in participants' knowledge about their own pleasure preferences, their confidence and positivity about that knowledge, as well as how pleasurable their sexual experiences were during both masturbation and partner sex. Many participants reported that after using OMGyes.com they felt more motivated to explore their preferences and more confident to explain their preferences to their partners. Our data suggest that OMGyes.com may be useful for positively impacting how women think about sexual pleasure, how they understand their own specific preferences, how they advocate for what they enjoy with partners, and how they actually experience pleasure.
