I have this anti turtle
sleeve too. I would say it stops me from turtling under 65% of my normal flasid size. The only thing I'm wondering about is how much blood flow does it stop. I never have any kind of problem with blood flow at all, but it has to stop some, sense it does hug tightly all around the penis shaft and head. To give you an example of how tight it is.. you can take a piss with it on, but its kinda like taking a piss with an erection, you can do it, but its not very easy.
Has any used this long term?
As a side note. I used this to recover from a blister I got on the head of my dick. It was really great for keeping the bandage on my dick while I slept and got night time erections. I'd say its worth having around just in case you do get a blister, which I hope you never ever do ever.
Anyways, I think I'm going to start using this now after my
hanging sessions to build up some data on this product.
