As the subject says, I own both pumps. After using the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98 ]X-40[/words] for one month and a week I can no longer tolerate the pain at the base. I tried to use the [words=https://officialhydromaxpump.com/?uid=6&oid=2&affid=98 ]X-40[/words] and my balls keeps going in and it kinda tickles me. I tied my balls with shoe lace but I don't feel comfortable. I asked for a clamp and someone sent me one so now I want to give out both pumps. I will stick to [words=http://www.mattersofsize.com/forum/penis-enlargement-forum/12539-slow-squash-jelq-nothing-give-me-better-expansion.html]SSJ[/words] and clamping. Contact me if you are interested.
