Yeah, but I need to see a proper measurement. If you have 30-31 cm as you claim in your comments, then providing a legit proof of 25 cm shouldn't be that hard, right...
Also, I still agree with this either way. It shouldn't be that difficult. Anyone that legitimately had a certain size, even if there was a slight variance, etc. it would be really easy to verify it. I've seen people lying nonstop in everything imaginable, just look around you. They do it in almost every single thing they try cheating or lying, even in the stupidest stuff possible or that nobody would even care about they do it and they always use some sort of excuse...
The real person would just prove it or at least attempt to do what they say and then at a certain point we can tell if people are just trying to negate it and then this thread is irrelevant/a fake. It's not like it's going to take much of your time to take the pics or proof they want so I mean at the end of the day I'm on their side, I'm just not skeptical and believe whatever is possible as long as it's within the realm of human possibility I'm not going to define this or that.
Plus, people will do a lot for a bit of money like $100, you can't expect to just walk in and get $10,000 like nothing or basically have the world record ngl... idk man all they're asking for is some basic proof, if you can't do what they say I don't believe you but at this moment I think it's possible.
Even if you were telling the truth and nobody believed you and you decided not to prove it, so what? Who really cares. If I wanted to see the biggest cock in the world I'll just find an elephant or tapir or whale or some shit it's a part of the human body, 51% of the human population doesn't even have one this isn't some life changing thing like someone has the cure for cancer and nobody believes them. Look at the stuff going on around the world.
Either do what they say or don't or you can tell yourself you're telling the truth and nobody believes you and don't care about the $10,000 and even on the off chance that was true it wouldn't matter whatsoever that's such an insignificant thing. It'd be a chip on your shoulder basically.
It's like that saying, "put up or shut up".
