I'd missed a few previous comments along these lines. I like to play with the pre-cum sometimes just by sticking my hand in, but also like to wear mainly dark jeans, either indigo or black, so I can get pre-cum spots without it seeming too obvious--more like a deeper colour. Don't like to do spots with light pants, and the public responds with disgust. Plus it feels really good if the jeans are stretchy to have my basket massaged with some of the pre-cum while walking and acting as if I were going on about regular business (which I often am, I like to do this while I'm doing other things.)
