Like a lot of people, I never measured bone-pressed before getting into PE. I just took multiple measurements over different days and found a consistent average of visible penis. Of course, I still measured across the top, parallel to the floor without pressing in. My average EL was 5.75” visible. I have gained since then, so I cannot go back and measure bone-pressed. At this point, I am 7” BPEL and 6 1/8” EL visible. My weight has not changed much, so I assume I was 6.625 BPEL from day one.
Assuming a 1” fat pad on average, this poll basically tells me that around 80% of all guys started with a 6” EL penis or smaller.
Yes, I believe strongly in BP for measuring, but no one gets credit for that extra inch standing naked in front of a woman.
