We Have Evolved To Find Sex Disgusting, Scientists Say.

It is true every once in a while the blogs find a niche study that proves that your vegan avocado diet is giving you cancer.  

Everyone is a fan of sex apart from incels, who would be fans of sex could they get a woman to have sex with them. Even though, I think this study from the London School of Hygiene & Tropical Medicine will never apply to me, apparently we all probably evolved to feel a certain level of disgust for sexual behaviour. 

The new study, published in the journal Philosophical Transactions of the Royal Society, found that there are six distinct types of disgust and that women may feel it more than men.

Researchers surveyed more than 2,500 people, giving them 74 potential revolting scenarios — including seeing someone with an obvious infection and listening to sneezes and bodily functions — and asked them to rate how disgusted they were on a scale from “no disgust” to “extreme disgust.”

The six categories of disgust were atypical appearance, lesions, sex, hygiene, food, and animals.

Respondents found that infected wounds were found to be the most disgusting scenarios and were closely followed by body odour. 

According to scientists ‘disgust’ is an emotion that may have something to do  with our evolution. This is the “parasite avoidance theory,” that argues we feel disgust because it used to help us avoid infections.  

For example, in the past unhygenic and smelly people could spread Cholera, open wounds could spread plague and smallpox. And sex could put you at risk of infections like syphilis.

“Although we knew the emotion of disgust was good for us, here we’ve been able to build on that, showing that disgust is structured, recognising and responding to infection threats to protect us,” said Val Curtis, a senior author of the paper who teaches at the London School of Hygiene & Tropical Medicine. “This type of disease avoidance behaviour is increasingly evident in animals, and so leads us to believe it is evolutionarily very ancient.”

The researchers found that in every category women rated things more disgusting that men — which follows the trend of men being more likely to indulge in riskier behavior.
