This is a serious question and should be treated as one. Id laugh more at comments like ” If this was the case then thunders wouldnt exist” I have the personal belief that PE exercises which involve an erection MAY contribute to hairlose in those people who are already predisposed to it and maybe even in some that dont.Think about it, DHT is caused by excess testosterone. Frequent masturbation and masturbating for long periods of time, or edging/bolooning will cause or definitely contribute and speed up the process of hairlose.
I also heard on this site or maybe on MOS a long time ago that even Kegals can cause production of DHT because it is signaling the brain that you are having sex and produces testosterone once again.
