I believe the length of mine is about 5 1/2 inches. When I have my boxer briefs on it feels fantastic. But, when unsupported it feels like it is going to fall off! I think, like everything else, everyone's skin is different. I have yet to have it adhered where it could not be pulled off easily . DJ says when adhered one must be careful and gentle when removing it, but I personally have not got it to adhear strong enough that any great care would be needed when removing LOL. I'm still working on it! I would like to shower with it, but so far, every time I have tried it is almost detached by the time I am ready to step in so I just wash it separately an sent it aside. I'm not sure if this is due to the size, my skin, or my lack of experience with the adhesive. But again, as long as I am dressed, it feels fine.
