Sexual health includes positive aspects of sexuality and the possibility of having pleasurable sexual experiences. However, few researchers examine how socioeconomic conditions shape sexual wellbeing. This paper presents the concept of "erotic equity," which refers to how social and structural systems enable, or fail to enable, positive aspects of sexuality. In part one, we use this concept to consider potential pathways through which socioeconomic conditions, especially poverty, may shape sexuality. Part two builds from this theoretical framework to review the empirical literature that documents associations between socioeconomics and sexual wellbeing. This narrative review process located 47 studies from more than 22 countries. Forty-four studies indicated that individuals who reported more constrained socioeconomic conditions, primarily along the lines of income, education, and occupation, also reported poorer indicators of sexual wellbeing, especially satisfaction and overall functioning. Most studies used unidimensional measures of socioeconomic status, treating them as individual-level control variables; few documented socioeconomics as structural pathways through which erotic inequities may arise. Based on these limitations, in part three we make calls for the integration of socioeconomic conditions into sexuality researchers' paradigms of multi-level influences on sexuality.
