I had unprotected sex with a new partner late one night, the next evening the skin under my pubic hair began itching, and I formed a bunch of red bumps resembling pimples in my pubic hair (but not on my penis) The are painful if pressed, but they itch more than they hurt. I have searched around trying to find out information on these symptoms, and the closest thing I find is genital herpes, except that I do not feel any other pain or sickness and my symptoms began less than 24 hours after contact - from what I understand herpes takes much longer than this to show. Another thing is that I did not shower until almost 12 hours after my encounter. Could this just be a rash from my uncleanliness the following day?
