In fact, this distinctive fragrance is nothing more or less than a combination of male semen, lubrication and vaginal secretions as well as sweat from both bodies during intimate relationships, says Sara Gottfried, MD, author of The Hormone Resert Diet.
In other words, these two pH react to each other to create new chemical properties, she says.
The odor that emerges after a relationship depends largely on the pH levels of each partner.
Vaginal douches, soap used to clean your vulva and sitting in bubble baths can change the pH of your vagina, says Darius A. Paduch, MD, Ph.D., director of sexual health at Weill Cornell Medical College. The food you eat can also alter your pH.
If your partner is protecting themselves with a condom, you can also expect to smell some odor.
Indeed, having intimate relationships, especially if they produce a rough feeling, can cause micro abrasions in your vagina, which can cause inflammation and lead to a specific odor, says Paduch. In addition, sweat, spermicides and lubricant all have an impact on the mucous membranes.
The smell in question should not smell bad or be suspicious.
