I till today don't understand how it exactly happened after only 90 seconds of use, but clearly I was sensitive to it.

The FDA themselves also have a limit of how much pressure should be used, I understand that the FDA is not the most trusted source around here, but if the FDA who says to take something, which ends up being bad (FIN), even the more so if they say NOT to take something, how even the more so you should listen to them.

I also spoke to an MD (urologist) about penis pumps, he explained that he's not such a big fan, since it doesn't actually bring in the same source of blood of an erection. The blood is coming from another source. He did explain in detail but it was a while ago, and I don's exactly remember all of it.
