Sexuality is a key predictor of relationship satisfaction, but sexual desire and satisfaction can decrease over time. Past work has found certain aspects of personality can determine who can better maintain their levels of desire and sexual satisfaction over time, but findings have been mixed. Charisma is a promising, yet unexplored, trait that could be associated with higher sexual desire and satisfaction. Across two studies we find that through higher sexual communal strength charismatic people report higher sexual desire and satisfaction, and this allowed for higher sexual desire in partners of charismatic people. The effects largely remained controlling for the Big Five and general communal strength. These findings provide initial evidence that charismatic people are more responsive to their partner’s needs, which is linked to higher desire and sexual satisfaction in established romantic relationships.
