Is funny I felt the same in high school. The measurements you stated were mine exactly! I’m now 6.75 X 5.5 which is ironic. I can get to 7.0 with pumping, but it last only for about 24 hrs.
It’s exciting though when you hit that kind of girth. Your in the 100th percentile. I can barely get in my wife and it feels amazing! I started clamping 2 X 10 and started noticing flaccid is now 5.75 sometimes.
My goal too is long term is 7 X 6 cemented gain.
Funny when I read your story cause it’s the same as mine, happy PE!
