Jack usually likes to take it shoulder deep in the ass, but today he was feeling particularly raunchy and tried urethral fisting on himself.

Urethral Discipline 

The ability for a male to control the stream of urine from the penis. It also includes the ability to control when and how much urine comes out. Having a high degree of urethral discipline ensures that one is able to accurately urinate in the bowl/urinal without making a mess.

I don't have the urethral discipline I had when I was a youth.

Urethral Sounding

The act of inserting a variety of objects into the urethra for pleasure. Including but limited to dildos, screwdrivers, screws, toothbrushes and specially designed sounding tools.

I don’t smoke anymore but many times I go urethral sounding with a lit cigar. I’ll sit there and tan while my cock smokes.

Urethral U-Boat 

When a dude decorates his dick as a German U-31 class u-boat, and inserts a projectile, such as a nerf dart, into his urethra, so that when he climaxes into his partner, the projectile will be launched into his choice of holes.

I’m searching for a partner to perform the Urethral U-Boat on.
