in my teens I used the foreskin for a quick orgasm but have been keeping skin back for many years. I find holding where the head joins the shaft lets me 'tug' as a cut guy could. I can use lube but masturbating dry takes longer, building up to a more intense orgasm.
Any others find the same?
I pull my foreskin back tight, dry everything off and dry rub the whole thing. I don't know about it taking longer but it sure feels better. Touching every tiny bit of my whole inner foreskin and glans is the best and playing with the glans by rubbing, squeezing, pinching and twisting it.
