Unprotected intercourse and one-night stands: impact of sexual excitation, sexual inhibition, and atypical sexual arousal patterns on risky sexual behaviors in women

Introduction: associations among sexual excitation, sexual inhibition, atypical sexual arousal patterns, and risky sexual behaviors have been reported in studies involving men and women. To date, longitudinal studies have not evaluated the predictive value of these propensities for future sexual behaviors in women.Aim: to investigate associations among sexual excitation, sexual inhibition, atypical sexual arousal patterns, and potentially risky sexual behaviors in women.Methods: overall, 2,214 women (mean age = 30.65 years, standard deviation = 9.91 years) participated in a baseline Web-based survey. The 1- and 2-year follow-up surveys included 396 and 382 participants, respectively. Correlational analyses and multiple linear regression analyses were conducted to analyze the relations between predictor and outcome variables.Main outcome measures: number of partners, number of one-time sexual encounters, and number of partners with whom no condoms were used during the 12-month periods before each of the three data assessment points.Results: all five lower-order factors of sexual excitation showed positive correlations and all three lower-order factors of sexual inhibition showed negative correlations with outcomes at baseline and follow-up. Atypical sexual arousal patterns, the tendency to become aroused in unusual sexual situations, and the importance of relationship factors, such as trust, for sexual arousal were the strongest predictors for sexual behaviors at baseline. These variables also predicted the number of sexual partners and the number of one-night stands at follow-up.Conclusion: the findings suggest that increased sexual arousal when experiencing negative mood might be a risk factor for potentially health-threatening sexual decisions and support the assumptions of the dual control model that sexual excitation is positively and sexual inhibition is negatively predictive of risky sexual behavior in wome
