The Effects of Alcohol on Self-Regulation of Sexual Arousal in Sexually Compulsive Men Who Have Sex with Men.

Individuals who meet criteria for sexual compulsivity tend to be more likely to engage in behaviors that may have negative consequences. Despite the clear public health relevance, however, little is known about the determinants of sexual compulsivity. This psychophysiological study examined self-regulation of sexual arousal in men high and low in sexual compulsivity, when sober and after alcohol consumption. A total of 43 men who have sex with men (MSM) participated and were presented with a series of erotic film clips. Two clips were presented after alcohol consumption (BAL .06), two other film clips were viewed when sober. Within alcohol conditions, one of the two films was combined with a suppression, the other with a no-suppression instruction. Genital responses were lower in the high sexual compulsivity group and higher during no-suppression conditions. The suppression instruction was not effective under sober conditions but impacted responses after alcohol consumption. This effect was more pronounced for the low compulsivity group. The findings suggest that sexually compulsive men are less successful in inhibiting their sexual responses, but only after alcohol consumption. The findings also suggest that sexually compulsive men may be less responsive to (researcher-selected) erotic stimuli.
