Switching to cotton underwear, especially when you go running and when you’re exercising, may help too, as sweat can collect under polyester which can cause discomfort.

Avoid washing with soap as this can be drying for the skin, and use an unperfumed cream wash which is suitable for sensitive skin instead.
