Ok so I just got my cable clamps last Friday and I have been super pumped to clamp.. However when I clamp my dick doesn’t stay hard, the blood gets out somehow. I don’t know why this is happening. I get a full erection and then clamp all the way to the last click and it still doesn’t hold it in. I was told to get medium size clamps. My EG is 5”. If any of you could throw me some helpful information that would be great, thanks.
