Vibrating penis sleeve (inner nubs·base ring)

A set that pairs a vibrating sleeve you fit over the penis with a ring that holds it at the base. The sleeve is medical grade silicone, so it sits softly against the skin, and the inside is covered with nubs that add stimulation. There are two vibration motors and the strength is divided into 12 settings.

The ring keeps it from slipping off

With a plain vibrating bullet or a sleeve on its own, it can slide down or the bullet can work loose while you move. Here the ring around the base holds the sleeve in place, so nothing shifts even when you change position. Not having to hold it with your hand is the biggest difference.

Two motors, 12 strength settings

With two vibrating units the stimulation is not concentrated at one point but split between two. The strength is divided into 12 settings, so you can start low and work up slowly. The nubs inside add a scraping sensation against the surface that is separate from the vibration.

Some people use it for training

Some buy it to reach climax repeatedly, while others use it the opposite way, practicing at withstanding strong stimulation in order to last longer during sex. Used that way, you keep the strength on a low setting and stretch out the time.

What to know before you use it

Because the set includes a constricting ring, you have to manage how long you wear it yourself. Release it at once if numbness or a change in color appears, and never fall asleep with it on. Use only water based lubricant on the silicone sleeve. The vibrating parts mean the whole thing cannot be submerged, so concentrate your washing on the sleeve.
