Penimaster Pro - Frustration with grey sluice/diaphragms

Hello again,

So I was actually hitting on a roll with the penimaster pro and upping tension / adding rods, just came up on a month a few days ago, and I was pushing the tension a bit further - and then the device shot back toward my body, I was terrified as I thought I tore my penis :o , but after calming down I looked and the diaphragm ripped.

So this was the sluice/diaphragm that came with the device, so I watched the videos again and installed the replacements to the best of my ability, I watched multiple times so I think I did it properly.

But then I wore it again for around an hour and a half, and it ripped again, and nearly as terrified as the first time. fun.  >:(

Now I have 1 replacement left, and I'm being careful with it, I'm noticing that I can't get good suction anymore so slippage is pretty common now, longest I can go is around an hour if I'm lucky. Also before the first rip - I was able to get my glans fully into the suction with one squeeze of the pump ball. Now it takes 2 pumps and it's beyond frustrating, as you have to unscrew and re pump and somehow keep your glans properly in.


I'm also looking at buying replacements for the diaphragms but it seems like they're sold out in the US from the suppliers I know of, would greatly appreciate recommendations here if anyone knows of a supplier that isn't sold out.

Feeling annoyed right now and figured some folks here might have run into this problem, saw on reddit that people aren't happy about the grey 1 size fits all sluice/diaphragm. Would really appreciate any tips / feedback, want to keep the stretching grind going.

Thanks.

I used PMP for 3.5 months. 7-8 hours a day. All I can say is that it takes a while to get used to the system. But I've never had this particular problem. It sounds like there might be a sharp edge on one of the plastic parts? Then you also have to be very careful so that you don't scratch the rubber with your nails when you install it. Otherwise, for me the gray rubber actually worked pretty well.

Ok guys I am going to let you in on a little secret I discovered....There was a guy on reddit somewhere who used the PMP and said he got rid of the internal diaphragm and only used the sluices. Well I tried it and what do you know...It works like a charm. I just clean the interior of the glans chamber with warm soapy water occasionally. The new grey sluices are pretty durable and keep a tight seal around my shaft. Also I only use 100% Silicone Gel from Astroglide. Just a small amount and the bottle lasts about a 6 to 7 months. Way more cheaper too. When I first started using the PMP it took me about 6 weeks to get things working like clockwork. I can now put the contraption on in about 1 minute. Hope this helps. You can DM me for further questions..

Hi, did you gain length with that usage time, or was there no change at all?

When I got Peyronies I noticed how my penis shrank. Especially when it was flaccid. When I used PMP, it pulled it back out. The penis is still a little shorter than it was to begin with I think, but PMP pulled out the worst of it. But it didn't do anything for the curve, unfortunately.

Thanks for the feedback. I only care for length and girth improvement at the moment. Good to hear I am on a possible solution with PMP.
