The Captus allows plenty of stimulation while preventing a full erection.
If you're looking for a cock cage that keeps your cock off limits, the Captus isn't for you. The Captus allows all kinds of access to your cock. You can probably even work a limp cock through the half inch opening between the bars, but it would be terribly painful once you become erect. The Captus allows plenty of access to tease and play with your caged cock, but not enough room for an erection. It's perfect for teasing and orgasm denial. You can get so worked up that you'll do anything your partner asks if it means a chance that you'll get the key.
The security of the device is enhanced by the hinged 1.4 inch ring, but it may be too tight for some. The included lock is required to secure the cage.
