I'm 12 and my penis leaks liquid lot. I don't have a foreskin. I don't have any problems, but I'm always leaking.
There three fluids that come from the male penis: Urine, pre-ejaculate fluid, and semen. Urine has a yellow tint and is a transparent, thin liquid. Pre-ejaculate is clear, has no color, is thicker, and feels slick. Semen is a whitish color, sometimes with a yellow tint, an initially thick when it first leaves the penis. A short time afterward it disolves into a thinner fluid.
I'm assuming that you are seeing pre-ejaculate fluid. This is produced by your Cowpar's glands whenever you are sexually aroused. Early on your body doesn't know when is the proper time to be aroused, so you tend to produce the fluid too often. It is just like your penis. It gets erect more often than needed when you first begin changing from a boy into a man. It will take a few years, but it will eventually settle down. Best thing to do is try to keep your mind off of sexual things as much as you can.
