"What is a Penis Plug "
What is a Penis Plug? A penis plug is usually made of Stainless Steel and is inserted into the urethral opening for sexual play and stimulation. There are also ones made of the highest purity silicone that seems to have great success in this form of play. 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 the highest quality Surgical Stainless Steel.

Penis plugs are a form of sexual exploration for both men and women. Men are the largest group using plugs, but women are getting into the act and catching up to us men fast. Some woman purchase these as a sexual aid for their male partners, but also are finding this form of play very pleasing to their own Urethra. Women usually require a smaller shorter plug.

Urethral insertables come in a variety of shapes and sizes. Some are known as Urethral Sounds, which are straight or slightly curved pieces of steel that were commonly used in the Medical field to unblock obstructions of the urethra. They have found  their way on to the pleasure seen and have been used for some time now to stretch or to increase the size of the urethra.

Another type of urethral insertable is the Prince's Wand. The traditional version require a piercing on the underside of the penis. The prince's wand is inserted into the urethra, then a threaded pin is inserted into the piercing and screwed into the wand. A ball on the wand can be unscrewed for elimination of fluids.

With the piercless version that I have created there is no longer a need for that painful piercing. There are many versions and choices available on my website.


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. The best lube that I recommend is a sterile lube like Surgi-Lube that can be purchased all over the net. 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 thru-hole, which has a hole through the middle of the shaft. These thru-hole models are designed for extended wear and for elimination of bodily fluids. IE, piss and cum. A Glans ring attachment is available to help hold the plug for extended wear. Most of us men do not have the ability to self retain so a Glans ring is a must. In my personal opinion a rubber Glans ring is much more comfortable because it fits the natural shape of your cock where as a Stainless Glans ring is round. Lets face it, most cock isn’t round. With so many different size and shape cock out there one size does not fit all. With a rubber Glans ring you have numerous choices in rings that are available at your local hardware store for that perfect fit. 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. There are also plugs that have a hoop on the end to give it that pierced look, without the pain of being pierced. 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 their plug to a tens unit for some Electro stimulation pleasure.
Now you know what a penis plug is, so man up and give it a shot.

HOW I CLEAN AND USE PENIS PLUGS:
As far as cleaning of your tools here is what I do to mine. I clean them in the hottest water that I can stand to the touch while using anti-bacterial, non-abrasive, lotion free liquid soap. Rinse off soap, cotton ball with rubbing Alcohol rub down, hot water rinse again. Alcohol leaves a residue so I always rinse good. Then I pat dry with soft towel, let air dry and cool down. Then into a safe place it is put away until next use. I always rinse under hot water to warm water before use again. Everything that I have told you is just what I do and in no way are directions in anyway. For me, I prefer to use Surgi-lube which is found all over the net. I also prefer to wear one of my plugs for a day, then a couple of days without. The reason is to never let my cock to become use to it. Kinda like when you get a piercing, after a while you forget you have them. I want to feel my plug. Thats the whole point.


HOW TO SIZE COCK RINGS:
Proper fit is very important. For a conventional cock ring, here's how to measure: First get hard, then take a string and encircle it under your balls and up around the top of the penis. Pull the string until you have a SNUG but comfortable fit. Mark the string on both sides where they meet. Take it off and measure between the marks. A tailor's measuring tape can also be used, if you happen to have one.
Divide this measurement by pi (3.14) and you now have the inside diameter of a ring that will fit you well.

"
Here are some examples:
If you measure 4 inches (102mm), then your size is 1-1/4 inches (32mm).
If you measure 4-3/4 inches (121mm), then your size is 1-1/2 inches (38mm).
If you measure 5-1/2 inches (140mm), then your size is 1-3/4 inches (45mm).
If you measure 6 inches (152mm), then your size is 1-7/8 inches (48mm).
If you measure 6-1/2 inches (165mm), then your size is 2 inches (51mm).
If you measure 6-3/4 inches (172mm), then your size is 2-1/8 inches (54 mm).
If you measure 7 inches (178mm), then your size is 2-1/4 inches (57mm).
If this is your first ring, and you appear to be between 2 sizes, go with the larger size.
While you are still hard, or even if you aren't, use the same technique for two more measurements: first around just your penis at the base, and then just behind the glans head. You will really enjoy the new Designer Head and Shaft Rings, if you haven't already. They're loads of fun to wear for decoration alone, but create exponential excitement when you're swelling and swollen.
