Urethral stimulation can be done with many things including sounds ( both smooth and beaded rods) urethral vibrators, catheters, plugs and even some types of piercings.
Plugs come in a wide variety of types, both solid and hollow, sizes and lengths, including custom made ones. Any type of urethral stimulation can be amazing but which type one prefers is more of a personal choice. Probability sounds are best known simply because they are easy to use, cheap, reusable and easy to clean. Custom made plugs can cost some money but many feel they are worth it for the fit. Most common type of plug are ones held in place by a stud thru a PA piercing screwed into the plug to secure it but some use a retaining ring over the glans to hold the plug in place as well. A key factor in any form of urethra play though is to use VERY CLEAN items. Urethral stimulation is not for everyone but those who enjoy it REALLY enjoy it !! | 
no.
Why would you plug your cock? 
ouch
Yikes. Wince
This does seem a little strange. But I guess it takes all kinds to make the world. 
My buddy and I are thinking about electrostimulation. Do any of you guys like this. Have seen some videos and looks like something I want to do. What models are the best? etc.
