My urologist had mentioned that I might want to try to use one of those things, but I was a little leery. It seemed a little creepy and artificial (as opposed to injecting yourself with penis-expanding drugs?), but my Edex injections are getting so danged expensive (they went up $15 on a four-dose supply, to $230) that I reconsidered the ole' pumps, especially since they are reusable and might be covered by my insurance. I checked on the Pos-T-Vac, widely advertised on TV, which is a medical grade device. A basic system costs about $150, although I saw a different brand medical-grade device advertised on the CVS website for $119. Not sure I wanted to make that investment, I ordered the Pumpworx Beginners kit, which is $18 plus shipping from CVS, and is classified as a "novelty device".
I've experimented with it 3 times, with less than stellar results, although I can see where the medical-grade pumps probably work better. The first time, I couldn't get the danged thing to seal very well at the bottom, so when I started to build up any suction it started to "whee" like when you slowly let the air out of a balloon. The second and third times I used it in the shower after applying hair conditioner to Little Man's shaft, and either the wetness or the conditioner sealed it well. I could only get a certain amount of suction, however, before the squeeze bulb would stay squeezed and could not be re-inflated to be pumped again (a safety feature? I dunno). I did get some impressive size going, but even after releasing the vacuum it was then difficult to get the dang thing off me! (It sounded like a champagne cork popping when it finally came out.) Before I could get the cock ring on to keep it engorged, the erection had already started going away. I know the Pos T Vac has a way to roll the cock ring onto the bottom of the pump cylinder so you can just roll it off the pump onto your shaft, so that might be another advantage to the medical-grade pumps. So far, though, I have yet to be able to achieve a sufficient erection for penetration, although it worked well as a masturbatory aid (I know, I know, EWWW! Hey, everybody poops and just about everyone masturbates, so get over it!) The results have been intriguing, though, so I may try to get the Doc to prescribe one of the "good" ones.
UPDATE, 08/04/2014: I went ahead and ordered a Pos-T-Vac from Walgreen's.... It definitely works better than the novelty pump, but I still haven't quite gotten the little fella all the way hard, yet, what with different size penis rings and pressure levels to try. I did try using the new pump with a 100mg Stendra tablet, and that looks promising. We'll see....
UPDATE, 10/30/2014: I had trouble getting the Pos T Vac to seal because I'm kinda hairy down there (the Little Woman jokes I should braid it) so I used clippers and some scissors and cut it very short but not shaved. The thing did work better, but I still can't can't seem to generate enough suction to get it hard enough for penetration (although it makes hand and blow jobs more interesting). It's funny how the cheap novelty pump seems to pull the little guy out to full length, whereas the Pos T Vac plumps him up more. I had him big around enough that when I pulled off the pump to check him I couldn't get him back in the cylinder afterwards, but he still DIDN'T get hard. Sheesh....
UPDATE, 01/20/2015: I've given up on the Pos-T-Vac because I just can't keep shaving down there, and the results were only a little better than the cheapo pump. NOTE: If you buy a Pos-T-Vac, get one with either the squeeze handle or the electric pump. The push-down pump requires you to push so hard that it actually made my abdoment hurt, after a while. I've been using the cheapo in the shower almost every day in the hopes that it might help my Peyronie's disease (see later post, "Using Penis-Enlargement Devices to Treat Peyronie's?"), and it kind of feels good to have the little man enlarged even if he ain't hard. Sigh....
