I've recently noticed red spots on the head of my penis after sex or masterbating. There is no leakage or pain. It looks almost like a rash but not really itchy. I always use condoms but have had unprotected oral sex. The rash is more irritated when i have aggressive sex. I tend to get really dry skin in the winter months but have never had this during past winters. Also, the redness goes away after a day or two however, some of the spots remain.
I have the same problem but I found out how to heal it. Before taking a shower dab petroleum jelly on the penis head. It will help moisturize the head and protect it from running water which can sometimes dry the skin. I use it on a regular basis and now the red spots are almost gone. Yes it looks alarming because of the redness and dryness but Im glad mine is pretty much gone.
