Sexual double standard (SDS) involves evaluating the same sexual behaviors in men and women using different criteria. The support for man-favorable SDS is related to sexual aggression and sexual victimization. Yet to date, studies have not examined the prevalence of SDS adherence. This study aims to identify the prevalence per gender and age of the Spanish population who adheres to the SDS typologies (man-favorable, woman-favorable, egalitarian, ambivalent) by considering sexual freedom and sexual shyness areas. A sample of 2,002 Spanish heterosexual adults (50% men, 50% women), distributed into four age groups (18-25, 26-35, 36-55 and over 55 years old), answered the Sexual Double Standard Scale. The results showed differences in the prevalence of SDS typologies by gender and age. By gender, a higher prevalence of the man-favorable typology was observed in men and a higher prevalence of the egalitarian typology and the woman-favorable typology was observed in women. By age groups, significant differences in man-favorable and womanfavorable typologies were found in both men and women. Based on the evidence of four adherence to SDS typologies, it is recommended studying the relation of these typologies with sexual aggression/victimization to design more efficient programs for prevention and intervention of sexual violence.
