Whatever but not bathmate , too long to explain again, i've explained about it previously.
So 100% AIR pump only.
Me personally most of the case would not suggest going over 1.75 wide .
Unless you are 7.5 length wise or 7 and pencil girth.
Most men need little bit more length..Usually, usually men are not 7 inch length wise.
First why this, because how pumping works...You make length gains when you fill the pump girth wise first...You make only very very little gains without filling the pump girth wise before.
And this girth gain will and can cement permanent in time...
Now you have girthier cock with the same length, and later gaining length with very girthy cock is harder..WITH PUMPING.
yes stretching can..But if you wanna gain length with pumping also...
you need to use narrow pump first, gain length wise first then slowly increase wideness and start gaining girth also...
That's why i suggest using over 1.75 tube only if pencil dick but long..that most aren't.
Third...1.75 girth is 5.5 , if you have 5.5 permanent cement girth, that's huge..2 inch is 6.3...try to put something that is 6.3 in your mouth.. Barely go past teeth.
So if you are 2 inch girth, real true 2 inch 6.3 circum...not almost , true 6.3 circum , 2 inch girth.. Forget good blowjobs...
That's why i suggest 1.75 tops.
I would suggest only more than 1.75 if you are under 1.75 if you are 5.5 girth wise, stop.
But this is personal opinion if you don't care about blowjobs then go ahead, get to the real 6 inch girth..me personally don't recommend.
