It amazes me how much knowledge some people lack about their own bodies. The issue of pre-ejaculate, or pre-cum, appears to confound as many men as it does women.
Women asking why they find spots of semen stains when doing their spouses' laundry, and then fearing their man is cheating or secretly jacking off (which is another issue completely!).
Men asking what the leaking is and why they leak so much...even without an erection.
Doctors are clear to point out that all men are different; some leak like an open faucet, others produce very little to none at all.
Pre-cum is a clear, slippery fluid produced by the Cowper Glands. These are located adjacent to the Prostate. During times of sexual arousal the fluid coats the urethra to cleanse it of ureic acid left behind after taking a whizz.
The slickness of it helps to lubricate the urethra to reduce friction for better velocity.
It also aids in lubricating the cock to reduce the friction of whatever it might be sliding against.
It's really great stuff.
But, what some guys - and many women, evidently - don't understand is that we don't need a boner for pre-cum to begin flowing. Extreme horniness and a lack of cumming can be one cause.
However, if a guy is constantly leaking, causing wet spots on his pants
(Henry, I hope you don't mind that I hi-jacked this picture in the interest of education)
and there is no apparent reason for it, it could very well be a sign of a Prostate infection. The infection irritates the Cowper Glands which then begin their job.
I can say from personal experience, a Prostate infection can get so bad as to clog the plumbing, preventing a man from cumming. And, trust me, you don't want that to happen.
