Braxton's quickie for the day...
Email question: How can I tell if my prostate is empty?
Two-thirds of semen is prostatic fluid. Therefore it stands to reason that an empty prostate will probably result in a dry (or nearly dry) ejaculation.
Because younger men (30 or less) are such prolific producers of semen, it's quite possible that it will require upwards of five orgasms a day to run dry. There's tremendous variance, but after the age of 30, ejaculatory volume dwindles, thus implying that the prostate drains with fewer orgasms.
Within the realm of e-stim, it's quite possible to perform a thorough milking by means of one extended orgasm. For many men, this is far from a quick process. If you seek a drained prostate, you will generally continue stimulation well beyond the orgasm, until a state of "dryness" is finally achieved.
