I have been using my tower now for close to a year. I started with 1, then 2, then 3 rubber bands then back down to 2. It was hurting pretty bad to put on and take off my tower. Someone suggested I take off the bottom foreskin gripper. That solved most of my problems. Except one. On my shaft I am getting one small sore right where the push cup edge touches my inner skin. It went away after my break at thanksgiving and it came right back. I went down to 2 rubber bands at this point and took another week break around New Years. Going down to 2 bands helped but the sore has come back and it is fairly uncomfortable. Does anyone have any suggestions?
