I’m not sure that it’s true, that it’s different in any significant way. It’s a soft tissue of the body. When you apply traction it stretches. Hold that stretch for long enough, it will become permanent. I’m sure some tissues are more resistant to that than others. They’re not all exactly the same in that respect. The ear lobe probably responds better, but the same general principles apply. Stretch it, hold the stretch until it becomes permanent. I think both you and Sigmoid have it right. Time is more important than weight. I’m sure there is a lower limit, beneath which stretching is ineffective with less than decades of time spent doing it. But max weight multiplied by max time is a good rule of thumb. But if you have to sacrifice one in favor of the other, you go for less weight, more time.
I’ve become suspicious of all the theories over the years I’ve been reading about and doing this. I’ve always been a hard gainer. And I think there’s a reason for that. I was already getting 100% out of 100% out of my penis. I think those guys who report A half inch in the first 20 days and an inch and a half in the first year never were near 100%. Just an example. There’s a thread here on this forum right now, where somebody asked if he should be doing jelqs with a full erection. I can’t even squeeze a dent in one of mine it’s so hard, except with all my might, let alone jelq. All I’d be doing is stroking off. There is no question that bare minimum, all this exercise improves blood flow. That I believe 100%. That guy is going to get to 100% hard in a few months, and he’s going to gain a 1/4 inch girth and 1/2 length doing next to nothing. Only because he was never at any time 100% hard, and now all the sudden he is. I have come to strongly suspect that the guys who report big and easy gains early, are getting them that way. They’re not really growing anything, they’re just moving up to 100% peak function. Then of course they report a slow down, and all of the sudden they can’t get anything, but with huge amounts of work. Yeah, exactly like me right, from day one. It’s not penis toughening, scar tissue buildup or anything else. It’s.. You’re now at 100%, it was pretty easy to get there, but to go the next step to 110%, it’s going to take 10 times as long, with 10 times the effort.
I can’t borrow your penis and wear it around for a few weeks and compare it to mine and say, man, yours doesn’t get near as hard as mine, or, wow, yours is even stiffer than mine. All I have is mine, and as far as I know, yous is exactly the same. And it isn’t. That’s a mistake to assume they are.
Look a the before and after photos of the big gainers, and you can see it in almost every case. The before picture, supposedly erect, is soft and barely half hard. You can see it just looking at it. In the after picture, the guy is genuinely rock hard and visibly bigger in all dimensions. What he accomplished is not stretching, but increasing basic function. My advice.. Take with a grain of salt all the wild theories for phenomena that can be explained very simply and logically by just common sense and common knowledge.
In other words there are two types of gains. That are not the same. Knowing which one you’re working on, is at least going to tell you what you’re up against.
