I am attempting to understand the science behind sleeves and how they are used to cement gains. Can some tell me that if they are literally squeezing the penis (kinda) how do they cement girth gains if they do at all. I can see how they would cement length gains but if wearing tight underwear and constricting yourself can cause loss, how is this any different. I have just received my Sillisleeve and am just trying to understand. If there is a link that explains it more clearly, please feel free to provide that as well. Still pending arrival of my other devices but I am excited and ready to go!
