Pretty good starting size bro! You're above average already. That girth should get you some "wow you're big!" Comments from women. I get that and my girth is 1/2" less than yours.
Is your 7" bpel or nbpel? Is that pressing the ruler into the bone or not?
With that Bathmate, do 5x5x3 routine Dld cooked up. You'll want a 2nd session of ldngh manual stretching to get that 2".
And patience. With really hard effort 2" may take you 1-2 years or more.
Get started, study, practice, adjust, repeat.

What Dld figured out for the new hydropumps, starting a couple years back, is to pump the Bathmate or penomet 5 minutes.
Switch to SSJs 5 Mins.
Repeat 3 times.
That's a basic pump routine to maximize your girth and length gains.
