So 4-5 months ago I noticed a slight pink patches of skin on my testicles. Didn't itch or burn or anything like that which made me actually forget about it. I recently saw a doctor around a month ago and he said I had a yeast/fungal infection. Gave me a cream and said it would clear up after a month, but it hasn't. It doesn't look like what I've seen online about yeast infections, just looks like a light pink patches of skin. Is it transmitable?
