The diameter of your
Bathmate pump, gets reduced if you use the comfort insert, thereby preventing your penis from expanding at girth/diameter.
You can think of it like you buy a new wider
cylinder. This simple act will increase the intensity further.
The WideBoy or the regular
HydroXtreme 7, I'm just curious?
There is much more pressure/vaccum in that pump when you remove the comfort insert. If you can use full pressure/vaccum when you do not have the comfort insert inserted, I would be really suprised.
When you remove the comfort insert, you allow the pump to use it's full potential.
It will be somewhat more uncomfortable, but you will be able to use your pump for longer until you max it out in length.
But remember when you remove the comfort insert your penis are now allowed to expand at girth, and you may or may not see as much expansion at length. — Are you expanding into the walls of the pipe, of the comfort insert?
Just trying to explain how I'm thinking a little deeper, from your main question. I hope that was okay.
