In other words, before pausing to allow ones penis to "deflate" completely, one should have managed to keep oneself extremely stiff, aroused, and "at the brink" for a good, long while, and then, instead of yielding to the urge to release, gently slow down, stop, and take a deliberate intermission, enjoy a snack, turn attention to something totally different for half-an-hour or an hour, and then resume the masturbatory teasing.

I've actually encouraged a phone-j/o buddy to do this, too, once, when we were enjoying a very pleasant and exciting fantasy together, and both trying to "make it last."  At a point when we were both teetering on the brink, and restraining our lust with difficulty, I proposed that we simply stop for an hour, and then get back on the phone to work ourselves back up.  It led to an extremely intense and delicious orgasm for both of us.

I think so many men are a little embarrassed about masturbating, and so, don't explore some of the ways that it can be enhanced and refined as a pleasure in its own right.

There really should be some orderly name for this sort of technique.  I think it's actually a bit safer to practice what I'll call "intermissions" instead of "edging," because very prolonged, unrelieved erections (several hours) can actually do some damage to the tissues of the penis (a urologist warned me of this, once).  I do remember, many years ago, prolonging an erection for many, many hours, and, later on, finding that parts of my penis were actually quite sore for a week afterward, not from chafing or rubbing, but probably from some damage to small blood vessels in side.

Taking "intermissions" in a long session, and allowing our penises to deflate, is probably a good way to enjoy the same protracted session without doing this sort of damage.
