Sexual excitation, sexual inhibition and a prevalence of sexual disorders among msm and heterosexual men

Abstract

Introduction

Dual control model of the sexual response (DCM) indicates, that there are two separate, but cooperating systems of sexual excitation and inhibition. Previous studies using DCM concept have shown, that MSM (men having sex with men) had higher excitation (SES) and one of the types of inhibition (SIS1) levels, in comparison to the exclusively heterosexual men. MSM also reported more frequent occurrence of sexual disorders (erectile disorders, premature ejaculation and decreased sexual desire).

Objectives

Comparison of the MSM and heterosexual men groups in order to verify erenow observed differences in sexual excitation/inhibition propensity and prevalence of sexual problems.

Methods

The sample consisted of two groups: 47 heterosexual men and 60 MSM. The participants have anonymously filled up questionnaires (Polish version of the Sexual Inhibition/Sexual Excitation Scales SIS/SES and the author's survey) via internet. Then statistical analysis was executed.

Results

Our findings have shown, that both groups were similar in their propensities for sexual excitation (SES) and inhibition due to the risks of failure in sexual performance (SIS1), while MSM scored higher on the inhibition scale, related to the threat of negative consequences of sexual response (SIS2). Heterosexual men more frequently suffered from premature ejaculation and less commonly reported decreased desire. There were no differences in the erectile disorders report between MSM and heterosexual men.

Conclusions

Our findings are mostly in conflict with previous DCM studies results. Several issues, just like method of sexual orientation assessment or cultural differences may had its impact on such results. More detailed studies on these issues are required.
