Insertable penis plugs, also referred to as a urethral insert, can range from 2 inches to eight inches in length and anywhere from 3/16 of an inch on up. These plugs can be made of steel, plastic or glass. Penis plugs can be solid or have a “cum” through hole. The ones with thru-holes allow you to ejaculate or urinate through them. These can be worn for long periods of time. Some are even made for electro-sex. The key is to make sure the one you are buying is made from quality materials.
The point of an insertable penis plug is to stimulate the urethra and have great masturbatory or oral sex. It also can be worn as jewelry.
Now to the reader’s question. You should start out with a plug whose diameter is small (3/16 of an inch), use lube and insert it slowly. Once you get past the widest point it goes in very quickly so be careful. To remove the penis plug pull it out very slowly. The challenge is the widest point which really stretches your urethral opening. Penis plugs can feel great. If you want to try something new, I recommend you give insertable penis plugs a try.
