Abstract
INTRODUCTION
Studies of ethnic differences in self-report measures of sexuality have shown East Asian women to be more sexually conservative and less sexually experienced than Caucasian women. There is also strong evidence supporting the notion of ethnic group differences in general measures of nonsexual psychophysiological arousal; however, there have been no previous studies exploring ethnicity and physiological sexual arousal.
AIM
The objective of this study was to explore group differences in self-reported and physiological sexual arousal in Euro-Canadian and East Asian women living in Canada; we also aimed to explore the association between level of acculturation (both mainstream and heritage) and sexual arousal in East Asian women only.
METHODS
Seventy-five women (N=38 Euro-Canadian, N=37 East Asian) completed a battery of questionnaires and underwent psychophysiological sexual arousal testing using the vaginal photoplethysmograph. They also completed a self-report measure of subjective arousal before and after erotic stimulus exposure.
MAIN OUTCOME MEASURES
All women completed the Female Sexual Function Index, Vancouver Index of Acculturation, and Sexual Beliefs and Information Questionnaire. Change in genital sexual arousal (vaginal pulse amplitude; VPA), and change in subjective sexual arousal were measured during exposure to erotic stimuli.
RESULTS
The groups did not differ in the percent increase in VPA induced by erotic stimuli, nor was there a correlation between VPA and subjective sexual arousal. Among East Asian women alone, neither heritage nor mainstream acculturation was correlated with change in VPA.
CONCLUSIONS
East Asian and Euro-Canadian women who show similar ratings of sexual behaviors and self-reported sexual arousal do not differ in physiological or subjective arousal induced by erotic stimuli in the laboratory.
