As this thread has pointed out, the amount of precum widely varies between individuals. Some never producing it, others, like junior, gushing pre when aroused. Years ago, like decades, I knew a dude who kept his genitals wet with pre with just the hint of anything sexual. His cock, balls and total pubic area stayed soaked from excitement. I consider me the 'happy medium" and after a time of edging during masturbaton, ooze enough to cause my foreskin to pop as it covers and uncover my dick head. During the last year I've noticed a difference in the amount, producing less, but still enough to taste from time to time. ;D
