The present study examined relationships among ethnicity, gender, alcohol consumption, and sexual behaviors in a community survey sample of 1,392 adults. Predictors included liberal versus conservative orientations (sex role orientation, religiosity); traditional versus liberal attitudes regarding sexuality, typical alcohol consumption patterns, expectancies regarding alcohol's effect upon one's sexuality, and frequency of alcohol use before sex. Findings are consistent with other studies indicating more sex partners among males than females and among Blacks (particularly males) than Anglos. Blacks also reported less involvement in oral sex than Anglos and Mexican-Americans--although observed differences for oral sex were more characteristic of females and less characteristic of unmarried nondrinkers. Unmarried Mexican-American males reported somewhat, though not significantly, more partners than did Anglos. Unmarried Black males (particularly nondrinkers) also reported more frequent risky behaviors than did Anglos. Divorced Black female drinkers reported significantly less frequent risky behavior than their Anglo counterparts. Alcohol use-sexual relationships were independent of psychosocial background characteristics and situated drinking (drinking before sex) was more strongly related to sexual behavior dimensions than were general drinking patterns.
