A couple of years ago (I'm 21 now) while masturbating I noticed that the opening of my penis had kind of stretched diagonally, so now it's teardrop shaped pointing downwards towards the left since i masturbate right handed. I am (unfortunately) circumcised. I always use lube now but didn't a lot when I was younger, especially around the time I noticed this.
It doesn't really show when my penis is flaccid other than the slit looks a little elongated, but when it's erect it's wider than it should be. Also, when peeing when my penis is semi or fully erect the stream is sometimes a little weird or a double stream.
It doesn't hurt but sometimes I have this stinging sensation or just general discomfort. The really annoying part is it burns sometimes when I come (I don't have a UTI or STD), which i think might be my semen touching a wound (if one exists).
Has this happened to someone here? If yes please tell me as much as you can about it and what I can do about it. I will see a urologist at some point if it's treatable but I want to have as much information on the subject before doing so.
Thanks in advance.
