Is there no way to get somewhat similar results, although not as good, without having to use this type of product? Jelq?r/gettingbigger is leading the charge these days. PEGym, Thunders, etc are archaic.

PervMcSwerve <- makes the best extender and notable community member. Googling his name will show his reddit handle and pornhub account where he walks you through modern methods.
A basic air pump and quality extender will get you where you want. There's no reason to have a small penis if you don't want one. However, like bodybuilding, programming matters and results aren't fast.
Good luck.
