I’m having the same issue. I’m also trying to put the inner wear on the same way, but it will not stay on. I’ve tried two sizes of innerwear with the second size being as correct as possible, but the testicular strap won’t stay around my sack (mine are very tight against my scrotum, and I’ve read the forum post about the ball stretcher) plus the band at the head of the innerwear won’t stay on either. I keep turtling out of it. I’m also uncircumcised, so it’s really difficult to get the skin inside the innerwear with just the head protruding out. It seems if the strap would stay in place the band at the head would too. Any suggestions would be helpful.
Also, I keep reading about the ES, but can’t find the product on the Stealth website.
