"Do I have a fishy smell during sexual activities?"

It is possible to have a fishy odor during sexual relations, but it doesn't necessarily indicate a problem. There are various factors that can affect body odor, such as the time of day, diet, daily activities, and even the menstrual cycle. Maintaining basic hygiene, wearing loose clothing made of breathable fabrics like cotton, and using mild, unscented soaps can help address the issue. If you have concerns or further questions, it's a good idea to consult with a healthcare professional.
