Do not wash with soap and shower gels as these will dry your genitals and aggravate the skin
soaps that are not perfumed and those that have a pH level to suit the skin. Baby washes will be fine too.
Wear cotton underwear and nothing tight.
Make sure that you have a good healthy diet and cut down on fizzy drinks, and processed and sugary foods. Fungus loves sweet.
Make sure that you wash your hands after using the toilet and wash your hands before touching your genitals.
