Nonprostitute women in the sadomasochism (S/M) subculture have been believed to be rare. A sample of 45 women from the S/M subculture of whom 34 were determined to be nonprostitutes was obtained. This sample is compared with a similar sample obtained by Breslow et al. (1985). Despite methodological differences between the present investigation and that of Breslow et al., interstudy similarities permit conclusions about women in the S/M subculture in addition to the fact that they occur with sufficient frequency to study. The women become aware of their orientation as young adults and most are satisfied with it. They tend to be better educated and less often married than the general population. A majority designate themselves as heterosexual but a substantial minority are bisexual. They tend more often to prefer the submissive role but preference for the dominant role or no preference are found with considerable frequency. Oral sex and bondage are favored activities.
