Is my penis normal?

I know this sounds sili but stay with me on this.

I have a Bathmate x40 and now a Mustang air pump.

No matter what I do I cant get much expansion on the midshaft/end (near glands).

My base girth goes up in the pump but never seems to effect me mid shaft etc.

I have seen pics of peeps with huge expansion along the whole shaft in pumps but mine is just at the base.

There is all so a very weird effect when pumping which i have only been able to see since getting the mustang as its all clear and I can see the base area it looks like when i pump the penis on the right side at the base is twisted looks odd its all most like a chunk of my penis is missing.

I will have to post a pic how and whats the best way to post penis pics here?.

Thanks again

With pumping, you have to enter the tube fully erect and maintain it throughout the session.
