Reading this, Bumper and I have similar problems. I had unprotected sex with a friend about 2 weeks ago, and a couple of days ago I started noticing slight reddening on the head of my penis along with bumps accompanying these red areas. The surface of the red area has increased since yesterday. I too have not experienced any itching, swelling, pain while urinating, or blisters or sore. The bumps and red areas are strictly confined to the head of the penis. I am going to seek medical attention, but am slightly hesitant, because all I can think of is that it is herpes or another STD, which I believe my paranoia may in the long run make myself believe that the condition is worse that what it really is.
