Effects of subjective sexual arousal on sexual, pathogen, and moral disgust sensitivity in women and men.

The present experiment tested a novel method of manipulating subjective sexual arousal to examine the effects of sexual arousal on disgust sensitivity. Participants were instructed to employ their own preferred methods of achieving sexual or physiological arousal in the privacy of their own home to reach a target state of arousal. Participants then completed the Three-Domain Disgust Scale (Tybur, Lieberman, & Griskevicius, 2009), which measures sensitivity to sexual, pathogen, and moral disgust. The sexual arousal manipulation caused large, homogenous increases in sexual arousal in women and men. In women, sexual arousal (but not physiological arousal) significantly reduced sensitivity to sexual disgust and marginally increased sensitivity to pathogen disgust. In men, sexual arousal did not decrease disgust sensitivity in any domain. Findings support the evolutionary hypothesis that sexual arousal inhibits sexual disgust, which facilitates an organism's willingness to engage in high-risk, but evolutionarily necessary, reproductive behaviors, an effect that could be particularly important for women.
