They are indeed dangerous. I've heard numerous stories of men being rushed to a hospital ER after a b-l-o-o-d vessel ruptured from using a penis pump.

Furthermore they don't work. They may cause a temporary increase in penis size, but the operant word here is TEMPORARY. After a few hours, or at most a few days, the penis returns to its original size.

For more information on this, see the "Penis Enlargement Scams" article on this very site.

i think if you go about it in a sensible way it can be harmless fun for anyone that wants to risk it. I'm sure you would realise when you are about to rupture a **** vessel, hopefully -and not be under influence of any drugs or alcohole which would obviously be a recipe for disaster ..yet I m sure many have tried while under influence

They can be dangerous but can be fun too. I dont believe they can give you any permanent increase in size but the sensation can be enjoyable. Fun for edging. I also like the sensation while stimulating my prostate. If you get one just be careful and smart about it. And dont buy into any claims that you will end up with any permanent increase in length or girth.
