Frequent Urination... But Not Really

Hi, i'm a 17yr old male and have had this probably for a few years that i've noticed. I just recently when to a clinic and did a urine sample and a 24hr urine sample, my doctor said there wasn't anything wrong at all, my urine was condensing properly and there was no sugar etc..

So maybe there isn't anything wrong, but maybe someone knows of something that can help cause it's kind of annoying. It seems that when I hang around the apartment and when i'm not really doing much I have to be every hour or two, but I can work a 7hr shift and only use the bathroom once, or I can go out fishing for 6hrs and won't need to pee untill I get back home. I don't have to get up to pee during the night untill usually an hour or two before I would regularly get up anyway, but I do have to get up while i'm trying to fall asleep (it usually takes me 45mins-1hr to fall asleep).

Anyone else like this? Or know of anyway to train my bladder to stop annoying me or any other helpful info would be much appreciated.

Edit: I forgot to mention that when I go to the bathroom, not a lot of urine comes out either, and my doc said that my 24hr sample was average, but on the low side of average (as far as volume is concerned).
