Sometimes it's easy to pump, sometimes not so easy

[Strider]

I've had my AMS implant since 9/22/15. At first it was nearly impossible to pump until I figured out that it really takes two hands to get enough force. Maybe once in 20 times, for some reason, the first few pumps take very little pressure. But most times it takes a lot of pressure. It usually takes around 10 pumps to get a firm erection. I'm wondering why sometimes it's so easy and other times it takes so much two handed pressure that squeezing that hard really hurts.

Another question I have is why does it usually take about 10 pumps, but once in a while I can still pump after 35 or 40 compressions. I'm guessing that each of these issues may be related to where the shuttle valve is. At least I imagine there is some sort of shuttle valve involved, and maybe it did not move all the way opened or closed.

Do others here have any of these issues or can anyone explain why this is happening?

Btw, many people have said that squeezing the pump gets easier with use, but so far I've not found it to be getting any easier. So how long does it take before it got easier for others?

I have had all those things happen with my AMS. I have had it for 8 months now and in the first few months experienced the very hard bulb, the suddenly easy to pump bulb etc. Now, though, it seems to have settled into a more regular pattern. It is easier to pump than when it was new BUT only to a point. I can pump with one hand for the first 9 or 10 pumps with some force and then if I want more I have to use two hands and can usually get maybe another 10 partial pumps in. I never get the 30 or 40 easy pumps any more, but they didn't seem to do much anyway. I wouldn't say it is super easy to pump though and I cycle almost every day.

It may have something to do with the size of the cylinders and how much saline is left in them from the previous cycle. The 10 or so pumps is in line with what AMS says is required for a full firm erection.
