Another thing I like to do. when you go to a hot tub stand in front of a jet slightley kneel and rest your arms on the side of tub let the jets directly hit your penis the sensation feels awesome. Other people may look at you funny but that adds to the. Thrill

Bud, you might try getting upright on your knees on a rug. As you work your meat, lean back to put tension on your glutes, thighs, and hamstrings. Play around with that sensation...bounce lightly. I shoot further and more intensely when I press back as I shoot my load.

Very nice! Gets you even harder.

A good one I have recently figured out, and is especially useful when in a cubicle, is sit right on the edge of the toilet seat, cross your ankles, spread you legs wide and lean back. This allows your cock to be at its max length and makes the full stroke so much better
