This research addresses the interrelations existing between trajectories of intimate partnerships and attitudes toward sexuality, sexual desire, and sexual satisfaction. It is based on a dataset of 600 adults aged 25–46 living in Geneva (Switzerland) and uses innovative multivariate techniques for clustering life trajectories. The results emphasize the diversity of men's and women's trajectories of intimate partnerships. Trajectories with frequent and short-term partnerships are associated with recreational attitudes and higher solitary and dyadic sexual desire. In contrast, trajectories featuring few or no intimate partnerships are associated with traditional sexual attitudes and less sexual desire. Women's attitudes toward sexuality are more strongly associated with their intimate trajectories than men's. This suggests that men and women do not develop their sexuality in the same relation with intimacy. The results are referred to the gendered master status hypothesis.
