HP-02-006 The proneness to sexual excitation and inhibition in MSM and non-MSM

Abstract

Previous studies has revealed the differences in the levels of sexual excitement (SES) and inhibition (SIS1) according to Dual Control Model of sexual response between groups of heterosexual and homosexual men. In the US population homosexual men were found to score higher on the SES and SIS1 than heterosexual males. Moreover, homosexual men were also found to report more common sexual dysfunctions, such as erectile dysfunctions, premature ejaculation and decreased sexual desire. The aim of this study was to verify that observations in the different culture background. 107 men (60 MSM and 47 exclusively heterosexual men) filled an internet survey which consisted of Polish version of Sexual Inhibition/ Sexual Excitation Scales (SIS/SES) and supplementary survey. MSM group consisted of men who identified themselves as gay, bisexual or any other variant. Men from comparative group declared having sexual contacts only with women. General tendency to react with sexual excitation (SES) and general inhibitory tone (SIS1) seems not to differentiate men who have sexual contacts exclusively with opposite sex and those who also have sex with men (both exclusively and inclusively). MSM group scored higher in the tendency to inhibit sexual response due to the threats related to consequences of sexual fulfilment (SIS2). MSM group complaint more often on diminished sexual desire level, while heterosexual men group more frequently reported problems with premature ejaculation. There were no significant differences in the erectile disorders prevalence.
