for Disease Control and Prevention (CDC) to measure high-priority health-risk behaviors among adolescents at the national, state and local levels.6 We address three questions in this article: What were the trends in sexual behavior among U.S. high school students during the early 1990s? How does sexual behavior vary by race and ethnicity, and how have these differences changed over time? And fi...

Men appear to interpret people's behaviors more sexually than do women. This finding, which has been replicated in scores of studies using a variety of methodological approaches, has been linked to important social concerns, including sexual assault and sexual harassment. This article provides a critical review of the published literature on gender differences in sexual intent perception, using...

The researchers developed and demonstrated reliability for a list of Rorschach sexual responses. Sexual offenders (n = 40) and child abusers (« = 40) took the Rorschach to investigate differences in these responses. These adult male subjects were randomly assigned to either a permissive or neutral instructional set, and hypothesized differences between groups were found to exist only within the...

Research on sexual selection shows that the evolution of secondary sexual characters in males and the distribution of sex differences are more complex than was initially suggested but does not undermine our understanding of the evolutionary mechanisms involved. However, the operation of sexual selection in females has still received relatively little attention. Recent studies show that both int...

Several explanations have been forwarded to account for sexual coercion in romantic relationships. Feminist theory states that sexual coercion is the result of male dominance over women and the need to maintain that dominance; however, studies showing that women sexually coerce men point towards weaknesses in that theory. Some researchers have, therefore, suggested that it is the extent to whic...

Males from different populations of the same species often differ in their sexually selected traits. Variation in sexually selected traits can be attributed to sexual selection if phenotypic divergence matches the direction of sexual selection gradients among populations. However, phenotypic divergence of sexually selected traits may also be influenced by other factors, such as natural selectio...

Past studies indicate that men generally report having had more sexual experience and sexual partners than women, as well as an earlier age at first intercourse. At least some of these findings may partially reflect different responses to certain contextual variables in research. College students (266 men and 463 women) were asked to anonymously report their sexual attitudes and behavior after ...

Previous research with primarily white samples of youth has indicated that sexual minority females have higher body mass index (BMI) and sexual minority males have lower BMI than their same-gender heterosexual counterparts, with sexual orientation differences in males increasing across adolescence. This research explored whether gender and sexu...
