My wife and I are monogamous and both have been tested prior to getting together. A couple of days ago we had sex and I noticed the next morning I had what looked like a carpet burn about half way down my penis shaft, no big deal right? The next morning when I got up I had a slight itch down in that area and I inspected the area and noticed about five small blisters which were filled with a clear very thin fluid as I touched them they popped really easy. So the next day after paying attention to it and keeping it clean I noticed even more blisters and where the existing ones were they had formed a sticky kind of crust. But there is no pain except a slight burn from open skin and there is no puss, swelling, or discoloration. So far it just keeps adding blisters or the ones that had popped are refilling with clear fluid. Please help!
