Female Urethra Plug Femsoft

Has anyone used one of these in RL or in play? They appear to be only available by prescription.

It's like a little self comtained foley ballon cath, but only for stopping the flow of urine. If used by an experienced person in a safe way it could be a part of a real pee desperation scene, or just a simple tool to maintain some control over a sub.

This looks amazing. I'm tempted to buy one online to try.

CDA. Have you tried this product? How did it work out?

Wow looks like a great scene product - or a device that will give an older incontinent woman her life back!

Makes me wish I really was a female.

Does anyone know if a prescription is required to buy these? The literature on their website is not specific. I would expect it to have the same availability as a catheter.
