A new concept in erection control. The Guardian is not an actual ring: it only goes part of the way around the base of the penis, preventing blood flow from exiting your penis while still keeping your erection firm for longer and much harder then normal. While you wear the Guardian fluid can flow through the blood veins in the frontandn reduces the likelihood of harming your penis due to suffocation. The Guardian Erection ring can be worn for an extended period of time without harm. This erection ring is recommended for longer, all night sex marathons. It is easy to fit and very effective as erection control.
