When I see Americans jacking off, I feel they miss a lot of the fun. First of all they need lube while almost every uncut cock provided precum, the inner foreskin doing the gentle distribution.
Then the Americans seem stroking the shaft more, with short jerks, while Europeans concentrate more on moving the foreskin, pulling up and down over their moist dickhead.
Americans seems wowed by using a flesight but Europeans already have their own natural fleshlight: grab wih your warm hand the warm foreskin and jerk it. No external inventions needed.
Then comes the sucking off. Giving head to uncuts is more rewarding because they seem more responsive to the one giving head. Not so strange: the hundreds of sensitive receptors in the foreskin transport a message of intense pleasure to the brain.
Then my personal experience giving head: I love the variation of sucking an uncut cock. When pulled back (just grab the balls down) it feels like a smoothly cut cock. But when not tightened, you feel the skin moving with your sucking, you can nibble with the foreskin, you can give tongue rolls under the foreskin around the head, making your partner crazy, etc. I have blowed cut dudes, boy, sometimes the thought flashed through my head I could equally have blowed a broomstick!
