Hi guys I was wondering how some people wear [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]extenders[/words] for hours at a time my penis goes numb and cold after like 30 minutes and then I can only go for sets of 20 minutes after the initial set of 30...maybe its just me and I didn't have it on a high resistance at all and only did 30 minutes at the max..can anyone relate? Any advice? I have the X4 labs [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]extender[/words] by the way..very comfortable too
