A sample of 321 undergraduate students was utilized to investigate attitudes toward sexual and nonsexual extramarital involvements and to explore correlates of these attitudes. The results indicate that a sizeable majority of the students were opposed to extramarital sexual involvement, while the majority also reported they would find several nonsexual extramarital behaviors acceptable. The group most likely to report the various extramarital activities acceptable were males who disassociate sex, love, and marriage and who are permissive with respect to premarital coitus.
