For you guys who "never" produce any pre-cum, rest assured that most normal males do in fact produce the stuff. That's because all physiologically normal men have bulbourethral glands (also known as Cowper's glands) and the function of those glands is to produce pre-seminal fluid. The function of that fluid is twofold: 1. It lubricates the urethra to provide the ejaculate an easier passage to its final destination and 2. Being of a high pH the fluid also neutralizes the acidity of any residual urine in the urethra, as well as neutralizing the normally acidic nature of vaginal fluid. While it is true that there are normal, healthy men who seemingly produce no pre-cum at all I believe that most such men just never leak any of the stuff and that their ejaculate contains the full volume of what their bulbourethral glands produce, thereby giving their semen the same lubricant and pH benefits to procreation. Pre-cum can collect in the ejaculatory ducts without ever leaking down the urethra.
I happen to produce a goodly volume of the stuff myself, but it almost never leaks out when I am absolutely rock hard. However, like others have stated, after a session of rock hard arousal (with or without ejaculation) going soft always results in a pool of pre-cum. I remember one girlfriend of mine who loved to have me chow down on her pussy (and she had the sweetest little pussy in town) but just wasn't into sucking cock. In our foreplay I'd gladly go down on her while she lied on her back and I was on all fours with my knees up beside her head. She'd gently stroke my cock as I serviced her pussy and the manner in which she did so would always keep me erect enough that I was on the ready for the penetration that would ultimately follow, but not really "rock" hard. When I'd flip around to mount her in the missionary position there would always be a huge wet spot on the sheet from all the pre-cum I had leaked.
Those who do produce a volume of pre-cum know what an excellent lubricant it can be. I've always thought that there was an evolutionary connection between that fact and the manner in which my own cock leaks the stuff. There are many women who don't produce adequate vaginal wetting nor Bartholin's fluid (the female equivalent to male pre-cum) to accommodate vaginal penetration and in ancient times (i.e. no baby oil, Vaseline or K-Y Jelly) that meant no sex, which is frustrating. Frustration in the man produces a relaxing of the erection even though he's still horny as fuck. If that in turn leads to the leaking of a bunch of pre-cum his continuing efforts to penetrate could very well lead to success. It's just a theory, but I'm sticking with it.
