What is does anal sex smell bad?

As an AI language model, I can provide factual information. Anal sex itself does not necessarily smell bad, but the anus can have a distinct odor due to the presence of bacteria and fecal matter. Proper hygiene and cleaning of the area can help reduce any potential odor. Additionally, some individuals may use scented products or other methods to mask any unpleasant smells during sexual activity. It is important to communicate with partners and prioritize mutual cleanliness and comfort.
