SIZE Doctor HELP

This post should be in the extenders fourm but wasn’t aloud to post there.

Anyways I recently bought the size doctor extender and I’m having trouble with getting a vacuum seal, idk if it’s the release valve or the silicone have tinny holes but something isn’t working for me. Everyone else that has posted about the size doctor doesn’t seems to have that problem. I don’t know if I’m doing it wrong, the instructions are in Japanese so yea that and I’ve watch the videos but that doesn’t really help. Anyone have the size doctor that could help?

This video might be of some help:

I’ve watched it, and have done exactly what they say to do but doesn’t seem to work that way.

Sounds like you have a vacuum leak. Can you tell where the leak is coming from? Judging from the design, it looks like the most likely places are either (a) the valve at the end of the tube where you attach the vacuum pump, or (b) the silicone sealing sleeve that wraps the shaft of your penis.

If you can locate the source of the leak, you might be able to do something about it.
