Natural Gains vs PE Gains

Hi, in an attempt to further understand penis enlargement and its related mechanisms, I’m trying to gather information from those who practice PE and are above 30 years old.

As some may know, natural growth of the penis is to be experienced until up to 25 years old for some males, and a very small proportion beyond that.

I myself am under 25, and have jumped from 6.3 to 7.0 inches BPEL in the past 8 months with minimal PE, and have never had issues with erection quality.

As such, I’d wonder whether much of the rapid results some see are simply a result of natural growth. This thread is hence addressed to those 30 years and above who have not had EQ issues and have seen gains. What exercises have you performed, and what is your take on why these yielded gains?
