The effect of chronological and theoretical birth order on sexual attitudes and behaviors.

Abstract

A survey designed to evaluate the impact that both chronological and theoretical birth order may have on sexual attitudes and behaviors was completed by 441 respondents (221 male, 220 female). The attitudes and behaviors investigated were aggressive sexual behavior, social relationship attitudes, emotional relationship attitudes, total heterosexual behavior, and total orgasmic behavior. The data revealed no difference between male and female in terms of total sexual behavior. However, males had significantly higher sexual aggression, social attitudes, emotional attitudes, and total orgasm scores. These results suggest that while there may be equity between the sexes in terms of heterosexual behavior, there are still significant differences between the sexes in terms of specific behaviors and attitudes. No differences were found on any of the scales based on either chronological or theoretical birth order. These results suggest that sexual behavior and attitudes may be influenced to a greater degree by biological and cohort factors than by sibling position.
