Yes. Most definitely. Pumping and Clamping go together like peaches and cream, in my opinion, followed up with dry jelqs afterwards. In fact, other than manual stretches and Fowfers, or the wearing of lead rings, I’d say that these three are pretty much all the PE I do anymore, and I do them all together ending with either masturbation, via vibrator, or sex.
Step 1. I surround myself with porn, because I feel it is very important to keep stimulated during the first session, (Pumping) Using a big vibrator on the balls and one pressed against the heating pad wrapped around the tube, I (milk/vibrate/edge) for an hour at full erection.
Step. 2: Clamping: I wrap an eight inch long, ½ inch wide stretchy strip of neoprene at the base, pulling it as tight as possible with each turn so it squeezes down the base leaving a throbbing baseball bat of a dick about the size of a Red Bull can at the end. No way to get a clamp around that, but no need to. Then, I place one medium sized CableClamp around the wrap at the base and click it once, then jelq in blood until I am erect and engorged. I click again after jelqing in one more squirt of blood. At this point I am fully engorged with a swollen dick I can barely get my hand around. If I try to click the clamp the third time, I usually break it. Two clicks with the 8” strip do it for me. Your mileage may differ, according to post pumped/clamped girth.
The secret to clamping, and being able to keep from breaking them, and getting the full engorgement is getting this strip of neoprene cut to the proper length. The width is easy, just cut it to the width of one clamp, about ½ inch is wide enough. The length however will differ with every dick. The wrap should be about as long as your BPEL, or just a tad longer depending how stretchy your neoprene is. Mouse pad is too thick, thus hard to work with, Ace Bandage is crinkly and rough on the skin. Theraband is to tacky, sticks and pulls tender skin. The wrist wraps are usually just right, but they are making them more complicated these days, with thumb supports and crap. You have to take scissors to them now, and remove any thing like magnets, or metal, or plastic supports. All you want is a narrow strip of soft, pliable neoprene. If you can save a little bit of the Velcro fastener at the end, this makes it easier to use, but sometimes you have to sacrifice this little convenience to get the right size strip.
Step 3: Now I edge. I place one big vibrator under my balls and the other against the throbbing, swollen, spongy, baseball batted dick above the clamp, and lose myself to my porn collection. Every time I get close to ejaculation, just before the point of no return, I stop. Turn off the vibrators, pop the clamp massage and squeeze out old stale blood, jelq in fresh blood, wrap, clamp and continue. I usually do this for about an hour, and then end with ejaculation. The coming at the end of the routine is a nice little reward. Sometimes I bend one of the ladies over and come inside her, or sometimes I just finish with the vibrator, but my pump/clamp/edge/girth routines always end with a gut retching orgasm.
After I come. I hit the shower, soap up and slip on one of the big lead weights. The only way I can get one over the post girth is with soapy water. I have to remove it the same way. I wear this ADS almost continuously, especially when jogging or swimming. I only take it off to sleep. It’s comfortable, no way can it slip off over the post girth-work bat, and by putting a thumb against my shaft just under the ring, it makes a great anchor, or fulcrum point for A-bends and dry jelqing, which I also do almost continuously. When I sleep I do bed Fowfers.
In my honest opinion, the above routine is how I have obtained, and maintained massive girth and flaccid hang.
I have given up, however, on erect length.
