The psychosocial sources of sexual interest in older couples

Sexual activity with one’s partner is an important component of well-being and is linked to physical, emotional, and cognitive health. However, it is unclear why some older adults are more interested in sex and some less so. Their own characteristics, those of their partner, and characteristics of the relationship may all be important. We define sexual interest as consisting both of the motivation to seek sex with a partner and willingness to have sex when asked. We measure this construct using data from both members of 953 couples in the National Social Life, Health, and Aging Project. We focus in this article on the impact of psychological and social factors on older adults’ interest in sex, as well as the impact of their partners’ characteristics on their own interest in sex. We find that individuals with high perceived positive marital quality, a more positive and open personality, a large network of family, and better physical health showed greater interest in sex. Characteristics of their partner generally had little association with sexual interest.
