That's a nice penis.
Before masturbating, I like to use Hegar dilators to stimulate the penis. It's a nice hobby. It is very pleasant when the dilator slides into the prostate. I use a Hegar dilator 13 mm, 19cm.
Often thought it would be so hot with one end of the beads in my cock and the other end in another guy's cock while jacking off. A mind blowing orgasm resulting, wow.
