Kinda New to This Thing...

Yeah, i'm 15 years old and i've been having slight pain while urinating since last saturday. I have no idea what could have caused it. The pain is bearable, and it basically feels like a little sting when the pee first comes out, but then goes away. I told my dad about it, which is really awkward for me, and he just said wait a few days and if it keeps up go to the dotor.

There's nothing wrong with my sperm, though. And the pee doesn't smell bad at all. And there's no real pain in my lower stomach. Plus, I don't pee that frequently unless i'm worried about the pain going away, if that's the case i'll keep doing it to see if it's bad or not.

So, is there something seriously wrong with me? What can I do to stop it?
