well if you doubt that opinion from the provider, go and get a 2nd one from a dermatologist.
yes i told him
an he said ''well its skin just like on any other part of your body and if youve had acne problems its the same for that area''
most of the things that would cause these symptoms std wise, won't show up on std testing.
have you shown these to your provider? if so, what did they think?
