Hey J1L, Can you please explain what spring, locked, and bridge stretches are? How do you set them up with the [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]SG[/words] and what method is the most effective? Also what kind of wrapping material do you use to make the [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]SG[/words] the most comfortable? My comfort strap split the other day so now I use the velcro cable ties which is perfect because I have a 100 pack and I only need 1 to get strapped in. I'm still having a comfort issue though, I feel that uncomfortable burning around the strap area. I've tried a thick layer of cloth and the foam material but I can only wear it 20-30 min. before it starts to get uncomfortable. Thanks
