Hi I noticed about week ago I had a bump on the shaft of my penis. I didn t pay any attention to it because I ve seen them before but but that was only after I shave so never thought anything about it. Two days after that more bumps appeared and the previous bump got bigger and more appeared in a cluster. Now four days since the first bump appeared I tried putting antibiotic ointment on it, the cluster disappeared but a new cluster has appeared. There has not been any discharge at all so I don t know what to think about it. I m going to get it checked out but I just afraid of what it might be. Can you give me your opinion of what you think it is before I go
