I got mine in the mail a few days ago. It fits pretty nice and I can see it will have great potential, but I'm not sure if I'm using it right.
First, all this talk about a "head swell". If a head swell is just what I think it is (filling the head with blood), then how do you keep your head swollen? I don't see any way to keep the blood up there, after a few minutes of leaving it along my head has shrunk back down to normal size. Not only that but my head will actually feel COLD, indicating that there's little to no blood going through it.
Second, how much of a stretch are you supposed to feel? After messing around with it for a while I decided the largest size fit me the best, even though I'm only about 7" BPFSL. When I attach the extender to my unit I have it screwed all the way down with the springs pushed in. After it's on I release it and then unscrew it 3/4" or so. At this length my penis looks stretched out but I don't feel any stretching at all. Is this right?
