I have light gray/white thickened skin on my vulva (the perineum to be exact). It itches sometimes but not often and the intensity of the itching is very low. My doctor said that she feels it may be vuvlar dystrophy but she said there's a slim chance of it being genital warts. However, i have had the Gardasil shots. What is my percentage of it being genital warts? I am 19 years old, 153 lbs, and 5'3". I have also had many,many yeast infections, due to uncontrolled blood sugars, that have caused me to itch a lot and maybe cause this problem. And also I am a type 1 diabetic, just for extra info.
