Hi, I'm a 14 year old Virgin who lives a normal, non-circumsized, non-sexual life apart from masterbating about every 3 nights, about half a year ago I started to notice that the head of my penis was slightly damp ever if I had not got to the toilet for a wile and so I pressed the surface gently with my finger and sniffed and I smelled slightly fishy 6 months on and I have noticed it's got slightly worse ( this may be because I'm masterbating more) also, I thought it might be some semen that I have failed to clean up. The thing that worries me most is the fact that when I look up what it could possibly be a STD or STI but from what they say, if it's a STD or STI it should cause pain and smell in the penis, but it doesn't hurt at all. Also I read that it could be a fungal infection but I can't see anything that could show signs of something like that.
If you have any idea of what I may have, please say, thank you.
