What the hell is it?
It's the clear (usually) fluid that comes out of the hole on the penis while masterbating. Some guys have a lot some have alittle and I've actually known guys that never have precum.

If you masterbate in intervals (never reaching the point-of-no-return), then you will get it. That's the way it happens to me.
Precum is a clear, sticky, slippery fluid that is secreted by the Cowper's Glands, which are two small pea sized glands located near the base of the penis. The Cowper's Glands secrete this fluid during arousal, before ejaculation. The purpose of precum is thought to clean out the urethra from any residual urine, lubricate the urethra, and set the right Ph balance, all in preparation of ejaculation to help the sperm survive.
However, not all guys get precum - some get lots, others have none, yet there doesn't seem to be any difference in fertility between guys who produce precum and those who don't, so whatever its purpose is, its not significant.
