Sometime in February, I had protected sex with a friend that is known to be around the block. About one or two weeks after that i notice some white pimple like bumps on the shaft of by penis. I went to a local STD clinic and tested negative for chlamydia, gonorrhea,syphilis, herpes was not tested.They doctor said it was molluscum contagiosum and iI've been treating it with a generic form of aldara. About 5 days ago I noticed a rash in my testicle area. Two days after that the rash became worse and I went to the ER. The physician on site said it was contagious dermatitis and ran another syphilis test for the bumps on my penis shaft. Last night i started noticing itching around my anal area and this has me extremely worried. What can this be? Could it be herpes?
