Sexual disgust is an emotion that functions to motivate individuals to avoid the pursuit or acceptance of fitness-compromising sexual behaviors.
Introduction
Sexual reproduction likely evolved because, relative to asexual reproduction, it produces offspring that are better equipped for battle in arms races against pathogens (Ridley 1993). In light of its evolutionary history, the fact that sexual intercourse can result in genital warts, herpes, chlamydia, and HIV (among other infectious diseases) can seem like a humorous counterattack from pathogens. Of course, the pathogens transmitted sexually are not necessarily the same ones that would benefit from a pool of genetically homogenous hosts; specific viruses and bacteria (along with other critters) have evolved to occupy a niche in the ecological space created by reliable genital-to-genital contact between conspecifics. These sexually transmitted pathogens –...
