Laugh if you like, but one of my kinks is to measure another man's cock. Length and thickness.
Carefully measuring, I take my time.
I would use a measuring tape from Ikea as it is easy to carry, then whip it out. I would measure the length, then wrap the measuring tape around the cock, to get the thickness. I do not do this all the time, but once a while. Most of the men I measure get a kick out of it, or in awe. Most like it when I measure thickness as they are curious. The biggest I have measured was 9 inches long and 6 inches around. He was really happy I measured him as he was curious about his thickness. BTW, the correct way to measure the length is placing the tape on top of the cock, not under. I be curious what you guys think.
