Wondered if any of you can guide me. I read somewhere, not sure exactly where, that after two hours of using the [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]SG[/words] it should be removed to allow blow flow. Certainly, blood flow is important. Is blood flow prevented if the device isn't removed? Do most of you remove it after two hours or is it safe to keep it on all day long except for occasional loosing for bathroom breaks? If you remove the device, for how long do you keep it off? Do you massage yourself to stimulate the blood flow then put it on? Trying to learn about the best way to do this. Thanks for any guidance you can provide.
