Yeah, I can make anywhere between a moderate amount to a whole lot. I've also gotten embarrassed by it at times, but hey, can't do anything about it. It is always there after I get hard, and if my erection decreases or goes completely down without cumming, the pre will run out like a dripping faucet. Foreplay and general messing around can be a turn-on or a turn-off for the other person, but when it is noticed at first, I usually say, "oh yeah, there'll be lots of that."
The worst was in 10th grade in a history class. I was bored out of my mind and was daydreaming with a hard-on during the class. I had the big textbook in my lap to cover it, then I heard my name called over the intercom to go to the office (my grandfather had died and we were leaving to head out of town). My dick had deflated some and I thought it was safe to uncover. When I did I saw a big wet spot in my Levis over to the side where my dick had been folded up and to the left in the crease of my leg. My best friend was sitting to my left and he kidded me about it--he later told me he never produced precum and thought I'd shot a load in my pants. |
