A lot of people do things they wouldn’t ordinarily do while drunk – and more than a few marriages have ended over the indiscretions of a drunken spouse. There is something magically horrible in alcohol, which makes us feel increased sexual desire, while losing the ordinary good sense to just go home at the end of the night.
But if you’re wondering why alcohol makes you so weak – take some solace from the humble fruit fly – alcohol intoxication can actually turn him gay.
It’s true, researchers have known that acute alcohol intoxication decreases sexual inhibition in fruit flies, but it turns out that when given repeated doses of alcohol, over a matter of days (designed to replicate the experience of alcohol abuse or alcoholism) male fruit flies, who are normally quite macho, will seek out other males for copulation.
The researchers say that fruit flies are a fairly accurate model for the neurobiological effects of alcohol on mammals, like humans, and research using them can help to explain human alcohol affected sexual behavior.
