dear patient dont be nervous for anything. and do not feel that you are suffering from some major problem.what i from your description is that you are just suffering from folliculitis
and due to low immunity it has just spread from ine afrea to other.so i would ask you to go to a dermatologist
.and you should frankly open up with the details of your sexual lfe to the dermatologist. the doctor will give you proper oral and topical treatment after looking at the lesion.
