Sexuality is considered by most religious traditions to represent general temptation, procreation or a way to strengthen emotional bonds. The purpose of this study was to determine if frequency of religious attendance and perceived degree of religiosity could distinguish between those students who have and have not participated in selected sexual behaviors. Data were collected from a convenience sample of undergraduate students (n = 408) at a southeastern university. Students voluntarily completed a questionnaire in a regular classroom setting. The questionnaire elicited information regarding the frequency of attendance at religious services, perceived strength of religious feelings, perception of God's view of sex, and participation in the following sexual behaviors: sexual intercourse (ever, last year and last month), giving oral sex (ever and last month), receiving oral sex (ever and last month), and anal sex (ever). Data were analyzed using both univariate analysis (chi-square and analysis of variance) and logistic regression. Results indicated that religiosity variables, especially frequency of religious attendance and religious feelings, were significant predictors of sexual behavior. Results should be considered by those working with college students in the area of human sexuality. (Contains 5 tables.)
