The Humm Dinger is a portable vibrating cock ring that can fit any size penis because of its super-stretch material. It offers 20 minutes of continuous vibration and an easy on/off switch. Batteries are included for immediate use.
I wish they had made this in a more manly color. Try asking the boyfriend to slip on a cute pink or purple cock ring, ha! Aside from the color, the vibrations were up to par. Good for a couple of uses.
