Abstract
Several sex differences in sexual psychology and behavior have been documented across cultures and across historical periods. These differences have been investigated almost exclusively in young adult samples, however. Using data secured from an older adult sample of retirement center residents in Southeast Florida, USA (n = 186, M = 67.00 years), we assessed the replicability of several sex differences in sexual psychology and behavior in later life. Results replicate the sex differences identified in younger adult samples, including: (1) older men more than older women report interest in a greater number of sexual partners; (2) older men require less time before consenting to sex than do older women; (3) older men more than older women prioritize attractiveness in a prospective romantic partner, whereas older women more than older men prioritize good financial prospects; and (4) older men report a higher frequency of sexual arousal and sexual fantasies than do older women. Discussion addresses limitations of the current research and directions for future research addressing later life sex differences in sexual psychology and behavior.
