I have a question. I just recently had unprotected sex and 2 days after i developed this pimple on the side of my scrotum. is this herpes or is it just a pimple? I was concerned about this and started to research the net and found that it says you usually get fever like conditions and itching in the area before a out break. I did not have any of these symptoms but i am still concerned. any help will be appreciated.
