Can anyone help with this problem, maybe they have a clue or been through? Bottom line is, my penis head(gland) on the left side swells while urinating, it looks like it's suddenly getting blood on that side for whatever reason and then gradually swells down in 20-30 seconds after I urinated. Yesterday I noticed while getting an erection that it did the same thing, but then later on both sides swelled normally. I think it's related to an artery maybe? But what could it be? I never had a hematom to be a tear, nor do I have problems with my erections or holding them so the penis do gets blood and acts how it should BUT apparently it also gets some extra on the left side, something I never had till a couple of months ago. Could it be due to excessive sex that I had 3 months ago ( I had a couple of weeks where I had sex 3 or 4 times a day with my gf, for like 3 days and then couple of days later the same ). Could somehow an artery got " damaged "? Wouldn't that mean pain also and difficulty in erection? Things that I don't have. I went to an urologist 2 months ago, he had no idea and he focused more on the prostate and fed me antibiotics which gave me a bad side-effect for a month and a half in my balls, but this swelling thing is still going on. I am planning to go to another urologist this week or the next one but this thing just really kills my mind at the moment and I already got plenty of other stuff on it.
