Can any guys explain how vibrating cock rings or cock rings in general feel? Textures? Tightness? Pros? Cons? Does it vibrate the head, shaft, testicles, anus, perineum? How does it change sex? How does it affect orgasm? How does it affect ejaculation? Do you recommend shaving? Do you recommend a lube? Does it go on when flaccid or erect? How does your woman like it? Which one(s) would you personally suggest and why?
