So uhm . . . how do you know its working? I'm really afraid these bands were just too big, despite the reassurances from you guys. It doesn't seem to be cutting off the circulation at all, the testicles are still warm and everything. It SEEMS tight, and it where its supposed to be, but but . . . I don't want to mess up! It HAS only been a week but . . . please reassure me again!
