Women’s multiorgasmic capacity has long been mentioned in the human sexuality literature. However, due in part to the conceptual vagueness surrounding this phenomenon, few empirical studies have focused on this topic, and our scientific knowledge is currently limited. This exploratory research is mainly aimed at providing a much-needed assessment of the profiles of women reporting multiorgasmic experiences. For this study, 419 sexually diverse women ages 18 through 69 who identified as multiorgasmic completed an online survey assessing variables pertaining to sociodemographic background, context and characteristics of a recent/typical multiorgasmic experience, relationships between multiple orgasm and sexual/nonsexual aspects of life, and sexual and orgasmic history. Data reduction analyses using principal component analysis pointed out that 15 variables of interest were distributed across six components, accounting for a large proportion of the sample’s variance. A k-means cluster analysis further revealed that four distinct groups of women could be parsed out. These four groups could be differentiated by three sets of variables—sexual motivation, sexual history, and multiple orgasm characteristics—suggesting that female multiple orgasm is not a unitary phenomenon. This research provides to date the most comprehensive picture of female multiple orgasm and helps refine our conceptual understanding.
