To help with excessive sweating in the vaginal and groin area, you can try a few things. First, make sure you are practicing good basic hygiene by cleaning the area with water and a mild unscented soap. Avoid using products like Vagisil. Opt for loose-fitting clothing made of breathable materials like cotton. These measures can help manage sweating in that area. If the issue persists or worsens, it may be a good idea to consult a healthcare professional for further advice.
