I tried both cock rings and ball sack rings, and I now always go for the latter. I also suspend a heavy chrome trailer hitch from the ring, which is a marine anchor shackle. The advantage of clamping off and weighting your balls?
-- Makes your balls feel like they are 5 pounds as they swing between your legs--very sexy as you walk around.
--Balls are bulgy and shiny (if you also shave them) and are way more sensitive to touch. The wrinkles are taken out of the bag this way.
--Pulls the skin of the cock shaft down, making it more sensitive.
--overall, doing this keeps me continuously horny--I even wear the apparatus to work! But must cream off in the washroom by 10 a.m. as I am so horned up by the feeling of my big package between my legs
--when you fuck a person or a Fleshlight, everything pulls and swings as you thrust to and fro, slapping your thighs and making you feel you are hung like an elephant.

don't risk permanently damaging your equipment to save a few dollars. Go on the internet and get one designed to work safely.

if people are that afraid of friends and family noticing, get a po box.

I use scunci elastic ponytail holders. The come real easy when your done. Since they're not rigid they won't cut off your circulation too badly and if it gets uncomfortale you can just pull it off or cut it in a worst case scenario.

Bought stainless steel rings at local hardware store. Don

I like the rings from the hardware store. Or get a Split Collar from Industrial Supply.

I have a couple - a beaded ring that goes around the base of my dick, and a silicone double ring that goes around the cock and the balls. I love them both.

Thanks for the link, love some of your Zoig stuff. Have been looking for inspiration regards cock rings and the "O" ring idea looks nice and easy.
