Hand Pumping

My brother showed me how long ago. I am uncut. I wrap my hand around my hard penis and pump up and down until I go off. That is the method I learned. Too much precum wets my glans and dulls the sensation. My wife knows I do it and does'nt care. Sex with a woman is just to messy sometimes, and takes a great deal of effort. I weigh about 300 pounds and her 200. I know how to make my penis feel good better than anyone else.
