What causes your clitoris to itch and burn?

Contact dermatitis: is a common cause. Have you used any products in the area that might cause irritation? I would recommend that you use only a soap for sensitive skin or no soap at all for a few days. If it doesn't resolve or worsens, it would be good to schedule an appointment with your gyn. HPV, herpes, eczema, and vulvar dystrophies are all possibilities that your gyn can rule out.
