If you've ever heard someone say "it smells like sex in here," don't think they're being over dramatic.
While some may be dubious, science says there's indeed a distinctive smell left in the air after after two people go at it, and it all comes down to your pH levels.
According to Sara Gottfried, M.D., author of The Hormone Reset Diet, the unique odor is a mix between semen and vaginal fluids in combination with two sweaty bodies.
As semen is alkaline (a high pH) and vagina fluids are acidic (a low pH) in nature, when the two blend together, they create a new substance with new chemical properties.
While the smell of each romp differs depending on each individual's pH levels, there are other factors involved as well. Darius A. Paduch, M.D., Ph.D., director of sexual health at Weill Cornell Medical College, says there are other internal factors that can impact the scent, including douching, frequently washing your vulva with soap, sitting in bubble baths, and even the food that you eat.
However, if the scent does smell off, it may be a sign to see your doctor.
If you've ever fooled around, chances are you've noticed a distinctive smell afterwards.
Even if you use a condom after a romantic tryst, you should still expect some whiff in the air. When you have sex - particularly if it's rough in nature or your partner is well endowed - microabrasions in your vagina can form, which can lead to inflammation-caused odors, Paduch explained. He also said sweat, spermicides, and lubes can contribute to the smell.
However, Paduch noted the smell shouldn't be labelled as "bad," and especially not fishy. But should it smell that way, it's recommended you visit your doctor. While it could be nothing, there's a chance there could be a bacterial imbalance in your nether regions, such as bacterial vaginosis. Paduch also added infections from your partner's semen could also be to blame.
