 [ Symptoms ] small red bumps on penis forskin after and head also pink irritation on base happens after masterbating or intercourse first thought it was contact dermatitis with my gf but it becomes irritated after masterbating too it is very mild and not that noticeable unless you know it is there when we were not using protection and had frequent intercourse it would become more severe and would flake the day after could this be a yeast infection or some kind of bacteria [ Disease ] i am sorry you are experiencing this it sounds painful and a little scary what you are describing sounds like a lump in the skin which is good because these are not usually anything serious like cancer also the fact you have a similar lump in the other armpit is actually good news in this case because scary lumps like breast cancer do not usually present on both sides at the same time you have a couple of options here you can wait to see what happens if this lump is a cyst it may eventually open on its own you can try applying warm moist compresses several times a day to see if you can draw out the fluid from inside the lump do not squeeze the lump or attempt to puncture lance or otherwise open it on your own this can lead to serious infection if the lump opens on its own allow it to drain freely by placing clean if not sterile gauze loosely over the wound you may apply antibiotic ointment to help prevent infection then allow the wound to close on its own you also could go see a doctor for a diagnosis if this is a large cyst you may benefit from having it surgically drained or removed if you develop a fever or more bumps you definitely should seek medical attention wishing you well
