The Penimaster is a joke.

I have tried all kinds of way's to hold the PM in place without cutting into the head or my tool. My newest solution, which seems to work well, is baby socks. I purchased three pairs for $4.00, and they have lasted over 6 weeks so far. The socks come in pairs, you have to cut the foot off the end and use two socks at a time, just pull them one at a time over your cock and then make sure the head is sticking out of the end of the socks. The socks are made of wool and are very comfortable to ware. There are no marks or abrasions on the shaft or the head. I can now ware my PM for 2 1/2 hours without getting the head purple through lack of circulation.
