When a male reaches orgasm, and the ejaculate is forced to remain 'inside' or redirected into the bladder, either by clenching or physical manipulation through the taint. This can be physically harmful. First wirteen about approx. 7 years ago in the used to be cool till they sold at and went totally gay Vice Magazine.
I thought maybe if I didn't actually cum I could just go over and over again, so I tried that injaculate thing by pushing hard under my balls when I came. No cum, but it felt fucking weird. Like, taking a piss but with nothing coming out; just isn't right.

Injaculation is sticking 2 fingers on your PC muscle near the anus to keep semen from coming out during the orgasm. The semen is pushed back into the persons bladder, prolonging the orgasm and causing some painfull pissing in the morning.

I had the worst injaculation the other day, it all came out of my mouth at the end though. So I'm fine, what's up with you?

When you go kaboom! And then you injaculate. You suck all the sexual juices back into your phallic member?
