TechnoTed: I agree with all of those erotic uses mentioned. In addition, I use one when doing my PC exercises; makes it feel reaaal good
and makes my pecker (oops, sorry Pecker... :
drool pre-cum. In fact, if you use it for several hours, you'll be amazed at the pool of cum when you drop your drawers...
And the extra charge you get when you cum during sex is worth the price the first time ;D Prostate massage is practiced all over the world except the U.S. and this device (and of course almost daily sex)
has kept my prostate the size of a walnut (no enlargement; and I've made it to a pair of sixes but feel and (I'm told look) two decades younger. ;D So keep the cum flowing daily (your prostate doesn't care if its sex or a hand-job; as long as that creamy honey is flowing) and keep your prostate massaged, one way or a'tother...those of us that have and use the Pro-State or the Aneros (same thing) love it. Check out their websites mentioned previously and read what users say, especially Aneros.
BTW: Your balls are almost worthless for loads of semen; they only contribute sperm, which is only 1% (yep, one percent) of the good eruption. Believe me guys, your 'glory-organ' IS your prostate, right RoysToy? ;D Good Times.
Sorry Pecker, I've never heard of a prostate that doesn't feel ecstatic when massaged. :'( But maybe you have extra sensory nerves in your glans-head to make up for it.
