I'm the same way. If I just start to think about sex, It starts flowing! It's never really bothered me, up until lately anyway. I recently found a fuk buddy that really turns me on, when I go over to his house, get naked and drop to my knees to start sucking his dick... I'm already pumping out the precum, It'll drip on his foot or run down his leg. He doesn't really hardly ever say anything, but I can tell he don't like it. I guess by the time it hangs off on cock and then drips, it has cooled off from the surrounding air.. and it feel cold and wet.. and slimy.
For myself, it's never bothered me, as mater of it kinda turns me on.. I've always just reached down and milked it and then licked it off my hand.
The second picture, when I took it, I looked down and had precum all over my shirt. it pissed me off.. but whata Ya gonna do?
