SISSINESS, TOMBOYISM, SEX-ROLE, SEX IDENTITY AND ORIENTATION

Masculinity and femininity have been studied by self-ratings in independent areas of research: one investigating personality traits considered masculine (M) or feminine (F); the other, behaviours statistically more common in one than in the other sex (sex-linked behaviours), The two approaches were compared for the first time in the present study of 66 male and 51 female medical students, Consistent with previous findings using the second approach, male but not female subjects' opposite sex-linked ''sissy'' and ''tomboyish'' behaviours correlated significantly with their reported ratio of homosexual to heterosexual feelings (Ho/Het), Ho/Het did not correlate with either sex's M and F scores, but high M scores in women correlated strongly with several ''tomboyish'' behaviours, As ''tomboyish'' behaviours are shown more strongly by women exposed prenatally to increased levels of opposite sex hormones compared to controls, the findings have implications for the biological theory attributing Ho/Het to such prenatal hormonal exposure.
