Urethral Sounds

A penis plug or urethral sound is made to stimulate the nerve endings on the inside of the penis. This is done by inserting a rod into the urethra. This rod is often only 3 to 8 centimetres long. But there are also some longer models. A penis plug can feel intense with masturbation or sex. This is because you stimulate both the outside of the penis and the inside. The urethra is very sensitive. When you insert a penis plug, you stimulate numerous nerve endings that do not stimulate you when you penetrate or masturbate alone. For this reason, many men experience that their erection is harder and their orgasm is harder when using a urethral sound.
