I mean, think about it, both taste kind of funny, smell kind of funny and everyone loves (or pretends to love) sucking them down. But did you know that most people’s favorite beverage and everyone’s favorite birth canal actually have a lot more in common than their ability to simultaneously turn people on and off? They’re also equally acidic! This is really exciting stuff, guys.
The pH of the vagina is quite acidic, averaging around 4.5 on the pH scale (7 is neutral). That's about as acidic as beer or tomatoes. Busy microbe communities in the vagina maintain this acidity. For example, lactobacillus, a group of lactic acid-producing bacteria, dominates the ecosystem in many women's vaginas. These beneficial bacteria and their acidic output likely keep nasty bugs from moving in and colonizing the place.”
Now, aside from keeping the bugs out, the level of acidity only has a partial impact on each “liquid’s” taste. Generally, the more acidic, the sourer, and the less acidic, the bitterer, but as any connoisseur knows, there’s a whole biography of factors that can influence a beer or vagina’s overall flavor profile. Still, the next time you’re feeling naughty and don't happen to have a lady friend to help you out, consider reaching for a beer instead. Science says if you close your eyes and just let your mind wander off, it'll all be over sooner.
