I have problems feeling much of any sensation during sex, and I'm hoping that a fleshlight will help correct this problem. I bought a Flight, and just like during sex, I can't feel the texture at all. It has been three uses so far, which I know isn't a lot, but is the Flight not the best texture to use to cure Deathgrip? I can cum in it pretty quickly, but it is a weak orgasm and I can't feel any of the nubs or anything. Is an STU better (more consistent texture) in curing deathgrip?
