Just tell your parents: "Yo, I think there's 'something' wrong down there, can I see a doctor?"

You don't need to get into specifics. If you just see a normal doctor they can refer you to a urologist. But yeah dude, you don't wanna regret putting something like this off. Think about it, if it worsens, you may never have a sex partner.

I really hope you love those PC games.
