Now, now, let's not twist the poster's words. No one is saying you should stop jerking off, but rather that jerking off should just be one part of the rich tapestry of your life! That if people had other hobbies, they might not be compelled to argue the exact definition of the word "twink" like it's a taxonomy in the animal kingdom and not, like most words, a communal term largely defined by its use.
Personally, I think we should live and let live. All about the personal freedom. If you want to call a thirty plus year old man with a beard and chest hair a twink, I respect your choice. Just as long as you respect the choice of me and everyone else in the room to give you judgmental side-eyes and scoffs in response. We shouldn't argue! We should passive-aggressively judge and badmouth behind each other's backs like good bitchy homosexuals. Maybe throw in an extremely thinly veiled dig into casual conversation every now and then. That's the proper way of things.
