We-Vibe Verge
Finally, a vibrating cock ring designed to pleasurably vibrate the wearer, not just the partner!  Strong and rumbly vibrations, coupled with its quiet operation, make it suitable for both solo and partnered play, and oh so much pleasure. 

Plus, did someone say "external prostate vibe"? This wearable cock sling offers powerful perineum vibrations, sending vibrations up to the prostate, without having to go inside.  Slip this bad boy over the testicles, so that the triangle hugs the taint. 
For everyone curious about prostate stimulation but uninterested in anal stimulation, this is the toy for you! 

Battery Life: 2 hours from 1.5 hour charge, magnetically rechargeable 
Features:
- powerful rumbly vibrations

Sex Educator Tip: The Verge needs to be put on when flaccid, surrounding the penis and testicles, using a generous amount of lube.
