I tried this a couple times, and yea it did worked, but i felt its not healthy to do it much, what i did to get 5-8 orgasms, its just to squeeze the tip of my penis when i felt i was going to cum, but i felt like the urethra was under too much pressure, and somehow the cum just went inside again, in only did it a cople times, and i havent tried again, i wonder if other guys ever tried this
