I agree that getting off by way of prostate massage is right up there with self-sucking as far as being the pinnacle of orgasmic pleasure! For a maturing stud...say over 65... the prostate enlarges significantly and the number of sensory receptors increases dramatically. As if that were not enough good news, extremely potent chemical substances are released into the bloodstream as the prostate engorges ( yes it gets very erect) which gives a sense of heightened sexual pleasure and euphoria, right up there with opium for many men! I had always heard that there was no bottom quite like an older man...now I realize that there is probably no other bottom receiving as much sexual pleasure as an older man! For such a man, having multiple successive orgasms by way of prostate massage is not uncommon!
