I have never been a fan of vibration on my penis, but I have changed my tune. Most vibration for men has been fairly week. Maybe that is saying something about my energy, but when I attached this vibration sleeve to my wife's Hitachi and used it at high level it was very pleasurable.
You simply attach the suction cup to the end of the Hitachi or similar vibrator then add your favorite water-based lube, insert over your penis and, for me, turn the wand to its highest setting. It didn't take long from there to reach ejaculatory inevitability. If you don't want to cum too quickly simply move the vibration to a less intense spot.
