Yup, I did. I also did clamped rolling pins. I can't recommend any sh*t like this because it's high risk, but it gave me unbelievable expansion. I had a crazy phase where I was trying all kinds of stuff, mostly clamping related, where I saw my girth at it's maximum size. I was a hard-gainer with girth, but was extremely conditioned and experienced in PE. I wouldn't recommend such extreme methods unless you're maxed out with all other methods.
Good news. I measured myself a few times over the past week or so with better EQ and it looks like I'm retrieving some of my lost gains. Hovering around 7.8" bpel and 4.7" Meg. Not bad start back at PE.
