I have a repertoire of methods according to mood and need....sometimes I have my foreskin right back and lightly 'tease' the ridged band until I reach full excitement and pleasure......other times I need to thrust using my full shaft length to feel fully aroused. When I was younger I could cum by just brushing the loose end of my foreskin. Innovation and experimentation are the names of the game!

I also masturbate by touching my cock and shaking it
