That video was very good. Very nice foreskin. I have a very similar foreskin and when I have a masturbation session I slide oval metal keyrings inside my foreskin and push them as far down my penis shaft as they will go. I use 3 keyrings so that each side of my penis is covered by them. The sensation of the friction of the keyrings between my penis shaft and foreskin is incredible. The tops of the keyrings stick out above my penis head a little bit so that my penis head also gets stimulated.
