The authors studied sexual attitudes in 328 university students from 10 undergraduate classes at a Hispanic-serving university near the Texas-Mexico border. Men (n = 128) and women (n = 199) rated their level of agreement with 38 items on a revised sexuality questionnaire. There were 283 self-identified Hispanic students and 44 self-identified non-Hispanic students in the sample. For the most part, these students agreed with one another, although there were statistically significant differences, with women being less permissive or more sex negative than men were on items relating to oral sex, premarital intercourse, love and sex, masturbation, Playboy magazine, and pornography. For the entire sample, 26 of the 38 items showed statistically significant gender differences. For Hispanics only, 23 of the 38 items showed statistically significant differences, with gender differences those of the sample as whole. There were 8 statistically significant differences between Hispanic and non-Hispanic students, with Hispanic students tending to be more conservative. The authors discuss findings that are contradictory to D. M. Buss's (1999, 2000) evolutionary psychology jealousy theory, namely that women in the present study were more jealous than men were on the sexual intercourse item.

Sexual attitudes were studied in 59 Hispanic university students, at a university in deep South Texas, near the Mexican border. Males and females rated their level of agreement to 42 items on a 1-to-5 scale. There were 31 items that showed statistically significant sex differences at the .05 level or better. For 13 items, males were more likely than females to endorse items reflecting sexual permissiveness, or other male cultural stereotypes (e.g., disapproval of homosexuality). For females, 18 items showed greater acceptance of certain attitudes, ranging from disapproval of masturbation, to feeling they had to have sex when aroused. Females showed significantly more jealousy than males on both jealousy items, one on partner sexual intercourse, and the other on partner emotional involvement, which contradicts, at least in part, Buss's evolutionary psychology theory of jealousy (Buss, 2000). Possible reasons for the findings are discussed.
