Abstract

Sociosexuality, i.e. individual's willingness to engage in uncommitted sex, is systematically higher in men than in women, and can be considered a male typical trait. However, intrasexual variation in sociosexuality is considerable, with individual femininity/masculinity being one of the factors influencing sociosexuality.

The aim of our study was to test, in heterosexual and homosexual men and women from Brazil and the Czech Republic, whether childhood gender nonconformity (CGN) and continuous gender identity in adulthood (CGI) are associated with individual sociosexual orientation (SOI-R). A sample of 1336 heterosexual and homosexual men and women completed questionnaires on CGN, CGI, and SOI-R.

In general, correlations show that higher masculinity in heterosexual women and higher femininity in both heterosexual and homosexual men are related to higher sociosexuality. Higher sociosexuality in masculine women can be explained by prenatal or actual androgen effects on sexual libido and can reflect a fast life history strategy.

In feminine men, this result might reflect female preferences for feminine characteristics in men and an overall shift towards male femininity which can increase individual fitness. Also, gender nonconforming individuals can be more liberal adopting behaviors which are considered as non-traditional.

This study challenges the widely association between masculinity and unrestricted sociosexuality.
