this is pretty weird... are you certain it is urine? Because the unirary tract is supposed to close up as you stimulate your penis, which in turn makes way for semen (hence why you can't pee when you're masturbating).

I'm going to be honest with you, i have no idea how this can happen unless;

1. you aren't really masturbating.
2. there is something wrong with your organs.

Make sure its urine that comes out and see if it happens consistantly, if it does or if you start feeling any discomfort/pain, see a doctor.

Then in that case you probably have a problem with your organs
I know it hard and very embarrassing but talk to your parents, but not a mom or another lady, ask your dad, brother, uncle, cousin, or any male that you trust, it should be a male cause they no more about male masturbation, and could most likely help you out a lot
Good Luck

You never mentioned your age, and i haven't seen anyone mention this yet. Is it possible you just hit puberty? and that the semen hasn't developed yet. If your young, it's probably a normal thing.



or....... It's most likely a precum or something...........

I doubt you have a problem, are you sure it's not precum?

I agree with leigh, if its clear and not that thick it is probably precum

Hmmm, piss before you wank is all I can really say about that.

it's most likely precum
