I live in Brazil and bought the penis pump shown in the photo. It worked well the first two times I used it, but now it doesn't hold a vacuum very well.

It seems to seal properly around the base of the cylinder, but air is leaking in through the piston/plunger. I'm guessing there's an issue with the rubber seal attached to the piston that's supposed to keep it airtight.

Unfortunately, there really aren't many good penis pumps available here in Brazil. Most of what I can find are cheap, generic models rather than anything high-quality or professionally made.

One possible solution would be to buy a better pump from AliExpress. However, I have basically no experience with penis pumps and don't know much about them, so I'd really appreciate some help finding one that is safe, reliable, and durable.

I'd also appreciate some help choosing the correct cylinder size. The cylinder on the pump I bought was way too wide for my penis, so the diameter was completely disproportionate to my size.

My erect measurements are:

- Length: 6.4 inches

- Girth/circumference: 5.3 inches

What cylinder diameter would be appropriate for these measurements? And are there any specific pumps or brands/models on AliExpress that you would recommend?

Love pumping with cock rings already on. Keeps it super hard

Definitely seeing improvements in my cock from all this pumping almost hit 9 inches today when i took it out the tube! Its so much more sensitive now that its filling the tube. Won't be long till an upgrade is in order 😆
