Urge to urinate very often.

[Et in arcadia ego]

Hi, I am a 17 year old non-sexually active male. Recently, I have developed an overwhelming urge to urinate often. Even after I urinate, I still feel the urge to go. While urinating, the stream is weak and not much comes out. Given my age, it seems like this is unlikely to be because of an enlarged prostate...what are some things that I can do about this?
