Though disgust is a universal emotion, little is known about how it emerges. It is assumed that disgust primarily helps us avoid contaminants and diseases. However, disgust responses are not always adaptive. For example, people with a phobia may experience extremely high levels of disgust.
What are the clinical implications of a less functional interplay between sexual arousal and disgust? If sexual arousal is low, then perhaps the disgusting properties of relevant stimuli for pleasurable sex, and the hesitation to approach these stimuli, are not suppressed. This can give rise to sexual problems.
Sexual stimuli are among the strongest elicitors of disgust. So how do people succeed in having pleasurable sex? We tested the idea that perhaps sexual arousal can temporarily reduce the aversive properties of otherwise disgusting stimuli, thereby lowering the threshold for engaging in ‘‘disgusting sex.’’
