Hello,
My name is Yaroslav, I'm 16 years old.
I have a problem with my penis. I didn't give it too much attention, but it's been a couple of month (years?) since I had it. The tip of my penis (urethra hole) is red and the skin looks kinda like lips. It doesn't hurt /itch or anything and when I was going through the medical check with my class, when looking at my penis, the doctor didn't say/write anything about it as far as i know.
It looks very aesthetically unpleasing.
Thanks in advance

If my english is bad, please excuse me
