i had initially decided to try the flesh tunnel route. i bought a few and even the smallest (6mm) i could not insert. i started the general stretching exercises anyways, noticed some slight increase, but still quite disappointing.
so i took the plunge and bought the Glansie. insertion was simple and i felt like the stretching was really working, with the really tight "ring" of the foreskin being targetted. it took a few days til i could reach the first "notch" on the deluxe and lock it off. i did this several times per day. once i could get the 8mm flesh tunnel in i would leave that in between stretchings. took about 2 weeks to get to the second notch.
i am now up to the 12mm flesh tunnel and the glansie can actually be inserted inside of it while worn and stretched, rotating it around to make sure im not just stretching in one direction.
once i am able to insert my fingers to do the stretching i am quite confident of even more progress. i have ordered some of the moldable plastic and plan on making one of those stretching devices for when the flesh tunnels can't get much bigger. seems alot cheaper, and a bit of fun with the molding as well
