Hi. About 11 days ago I engaged in unprotected sex with a girl who still swears she's clean of any std's. About 9 days after the act, the right side of the head of my penis became covered in painless red rash. The rash consisted of small, almost impossible to make out red bumps, surrounded by reddened, irritated-looking blotches. These gave way to a dry, cracked appearance on the right side of the penis head, with some of the cracks stretching towards the left side. I am experiencing no itchiness, but slight pain if the cracks are jostled. I'm scared to death. I'm convinced it's herpes, as a few websites have stated that painless redness or dry areas can be considered atypical symptoms of herpes. I'm going to get tested for std's tommorrow, but my anxiety is eating me alive. Please help me. Thanks.
