Last night the shaft of my penis (below the head) and my scrotum itched and became very swollen. They are now oozing a clear discharge. I trimming a large euphorbia plant most of the day in only gym shorts. Could this be some sort of reaction to this? I am a 58 year old gay male that has had some casual non-anal sex recently. There is no pain and there are no sores or blisters.
