I also suggest and recommend, that you start to pump with water. With water you're able to get more temporary expansion in a very safe way.
That is at least my experience. I have never got a blister on my glans or anything like that. Just clean big expansion without these side effects. Just a little bit fluid retention after session, but that is okay.
I haven't the best air pump to compare it to (cost only ~$50) but with water pumping (Bathmate) I can go with really high vaccum without any problems.
With the cheep air pump I have, the glans start to hurt if I use to high (optimal) pressure.
Maybe I should not write about this (lack of experience with any good air pump), but as I have grown really fast with water pumping before. I want to recommend it.
My belief is that you will fix this imbalance you have in girth, with water pumping and with

You can water pump with the
MityVac pumping system as well.
