I’m about 7 months in, adjusting to life with an implant…I’ve had my ups and downs, including a tough recovery and my partner initially not liking the feel of the implant (we had to get creative because of the slight downward angle), me having loss of sensation…but now I like having a working penis on demand.
However…when I deflate and squeeze my penis with my left hand while pressing deflate button with my right, I get a soft flacid, but after about five minutes some fluid flows back in (I have Classic, NOT One touch). I actually like the feel and look of having it partially inflated! Since I’m not that big, I don’t have a noticeable bulge…but then I started reading and I discovered this site. I decided on a new post (after being a lurker) rather than respond or post a question to an existing thread:
Do other guys have this situation (is it a problem? Idk) of backflow or some auto inflation? If so, is it something to be concerned about?
Also, do some guys just keep it partially inflated on purpose for the better look and feel?
I’m hoping there are some guys out there further along than me who can reassure me that leaving it partially inflated won’t lead to any problems down the road. Thanks in advance.

Re: Coloplast Titan Classic doesn’t fully deflate
Well, I also have a titan classic and I have the same problem. What percent is yours inflated? I’m going to guess that mine is about 30%. I used Dr. Eid and he said that having it inflated all the time will lead to shrinkage of the penis. Since I am the exception who has had a poor experience with Dr. Eid, I’m inclined not to believe him in this case. I wrote about my situation here if you would like to look at it to see how it relates to yours:

Re: Coloplast Titan Classic doesn’t fully deflate
I just don't understand the logic behind if you don't deflate it your penis will shrink. Isn't the scope of inflating it to stretch the cylinders in the cavernosa? So it should be the opposite.

Re: Coloplast Titan Classic doesn’t fully deflate
There is no problem here. You are fine.
I have the same implant. The Coloplast Titan with the classic pump.
When I deflate fully, my penis looks quite flat at first. Like yours, a minute or two later, it’s not as flat. But keep in mind that no matter how much you squeeze, there is part of the cylinders deep inside your body and you can’t squeeze them. When you let go of the cylinders, fluid from the part you can’t reach will flow back into the flattened part you just squeezed.
As we heal, scar capsule forms around the implant. As long as you fully inflate and fully deflate (even briefly) on a regular basis this isn’t a problem. That is why cycling daily is recommended for the first several months. Then periodically after that.
One problem that has been mentioned here is guys who failed to fully inflate and deflate regularly ending up with scar capsule forming around the reservoir. That restricts the implant’s ability to fully deflate. If they left their implant partially or fully inflated for long stretches of time (days/weeks) without fully deflating, the reservoir gets restricted by scar capsule and it can’t stretch enough to accept all the fluid from the cylinders.
You don’t have to stay fully deflated more than a moment to give the reservoir the stretch it needs. So just fully deflate and fully inflate once a day and all will be well.

I'll be getting a Titan, so this is all interesting to me.
Is it possible the fluid coming back into the cylinders isn't autoinflation per se, but instead residual fluid left in the tubing after deflation that finds its way back into the cylinders due to gravity or movement?
I was given to believe that adding a slight amount of fluid to the implant was the standard way of alleviating the dog ears, now I'm a little confused about whether that is really a best practice.

Dr Eid would tell you that the implant should be stowed as 100% completely deflated as you can get it

I haven’t had problems with dog ears. When I am maximally deflated my cylinders are flattened and if they bend there is a folded/dog ears but it’s not painful and I don’t feel the need to add fluid.
In my post above about my cylinders not being completely empty I meant fluid left in the portion of the cylinder inside my cruz that I can’t squeeze, not fluid left in the tubing. When I stop squeezing the distal part of the cylinders I CAN reach, some fluid from the internal part of the cylinder I can’t reach flows out into the distal part.
I’m guessing the same is true of the tubing (a little bit in the tubing under higher pressure as I’m squeezing the cylinder flows in the the cylinder to equalize pressure when I stop squeezing) but the tubing is such small diameter the amount of fluid would be negligible

This is reassuring from someone who has the same implant, thank you so much for your input!

Think most of the discussion here is very accurate.
I just switched from the OTR to classic pump after tubing break. I usually keep some fluid 10-20% in the implant to correct the dog ears. Not painful or bothersome at all, just don't like the unnatural look of it. I will deflate completely with exercise or sports to avoid injury.
I have noticed some more back-filling with the classic pump when completely deflated vs OTR. When i have some fluid in the cylinders not much of an issue. maybe something with the design of the valves between the pumps?
I don't think keeping the implant inflated will shrink the penis. I was told by patel that prolonged cycling can thin out of the natural tunica with the coloplast implant since the material is very stiff. This can worsen the dog ears over time and lead to more wear/tear on the valves in the pump itself (not the cylinders because they are very tough vs ams). I would think the penis would enlarge with coloplast cylinders and the material with cycling or prolonged inflation.

This discussion has been very helpful and reassuring to me (I hope it is for the original poster as well). I’m feeling fine with the way mine feels and looks now (even though I don’t think a Titan was a good fit for my body type). I’m ignoring what Eid told me and his suggestion that he make an incision in my abdomen to take some fluid out of the reservoir, something I’ve never heard of before and which sounds risky in terms of infection.
