A penis plug is a piece of stainless steel that is inserted into the urethral opening for sexual play and stimulation.
I need to express right now that, although some men have tried experimenting with objects that you find around the house, it is Very unsafe to use household items. You will also find web sites out there selling plugs made of things like glass or beads, but there is too much danger of breakage. Please only use penis plugs made from stainless steel. Penis plugs are a form af sexual exploration for both men and women. Men are the largest group using plugs, but women are getting into the act, too. Some woman purchase these as a sexual aid for their male partners, but plugs can also be used by women. Women usually require a smaller shorter plug.
The most popular form of urethral insertable is the Penis Plug. A penis plug does not require piercing and has the largest variety of models. There are solid plugs that are used mainly for urethral play. Your first thought is that it is going to hurt, but quite the contrary. The feeling is very difficult to explain and I'm sure it's different for every man, but the best way to explain it would be that it is like having an orgasm from the inside out. When using a plug for the first time, always clean your plug and use a good water based lube. Then relax. If you tighten up because you think it will hurt, you will never get it inserted.
Penis plugs can also come with a through-hole, which has a hole through the middle of the shaft. These through-hole models are designed for extended wear and for elimination of bodily fluids. A Glans ring attachment is available to help hold the plug for extended wear. Penis plugs come in a variety of lengths and diameters, so there is one for every penis size. You can get plugs that have a smooth shaft, or plugs that have a variety of lumps and bumps, each giving you a different sensation when inserted.

In the last few years there has been the addition of vibrators to the tops of the plug for an additional thrill. Some men also find it stimulating to attach there plug to a tens unit for a bit of a shock.
