Brainlets who've never heard of priapism. Getting a bigger dick from it is literally a very well know, well documented fact. Of course the size increase often comes with permanent dick damage. But the idea that dick size can't be changed is 100% wrong
Dicks can be stretched like earlobes, lips, nipples and many other body parts. There are literally tribes in africa and india where they stretch their dicks. You can find clips of pajeets lifting weights attached to their dicks
Besides even the best, most elastic materials always have permanent plastic (ie permanent) strains after loading.
I'm not even saying that dickmaxxing is safe or worth it but you're 100% wrong if you think it's not a thing
Nowhere near as much from what I've heard. I've also heard it gives you a weird mushroom or baseball dick shape when the increase is active. Not sure if that's true tho
