Squeeze method??...?!

Squeeze method??...?

I want to ask a question to those who've really done this.coz I tried this once,with myself only..when the "point of no return" came unto me, I immediately squeezed my penisreally
hard to ensure no semen would pass, I forgot if it's the base or just below the shaft though.. but I got a little scared coz the semen, that should've been exploded outside like
exploded inside my penis and came back where it came from inside.. some of it still came through outside also but only little amount and too watery.. Now I'm planning to try it
again, and with my gf.. but can anybody tell me if it's really effective?.. and doesn't it have any negative effects? Or won't the *** explode inside my penis and injured some nerves
inside? thanks! ^^

The method to block the ejaculation for getting a longer sexual intercourse works squeezing the penis just an instant before the orgasm is arriving. Preferable squeeze at the glans base including foreskin, but any other part is good because it just is the pain to block the coming orgasm and not a particular zone! If you press down while the sperm already is arriving it's useless and then the sperm will be leaking slowly because coming back in urethra and bladder.
At last don't forget that such a "coitus interruptus" (onanism) isn't a good contraceptive method. Back effects?
Remember that if ejaculation does not occur there may be a lingering sensation of heaviness, aching, or discomfort in the testicles due to the continued vasocongestion. This unpleasant feeling has popularly been called blue balls, perhaps because of the bluish tint that appears when blood engorges the vessels in the testicles.
