Hello Doctor: For the last 3 months or so, I´ve had this small, "dome" like bump, in my pubic area, just where the penis begins. It looks like a pimple. Its "skin" colored and its only one. When I first noticed it, three months ago, I went to the doctor and he said it was foliculitis, and he gave me salicilic acid. To be honest, I didn´t use it every day, in fact when I noticed that the bump reduced it self, I stopped using it.
