Sometimes the simplest way to do something can be the most effective, and that's certainly true with this straightforward cock ring! Simply slide the stretchy band over your erect shaft, and use the little toggle to adjust to the correct size! Such a simple way to get a firm grip on things!

Once it's in place, continue as usual and enjoy longer, harder erections and a heightened sense of sexual stamina! Easy as pie!
