I don’t know about jelqing totally flaccid. I’ve been at it about a month, and feel the most when I’m in the 40% erect range. Usually when I start jelqing I’m slightly plumped, if you jelq while doing kegals, it should engorge enough to where you start to feel it’s doing something.
I’m also uncircumcised, and jelqing hasn’t been much of an issue. The guy in the video just jelqs and ignores the foreskin bunching up over the glans. I tried it that way, didn’t really care for it. So now I do it two different ways. If I wet jelq, I start holding the skin to the base with the opposite hand as I jelq. It’s natural once you get a rhythm, since you’d be jelqing next with that hand anyways. I just start setting my grip while I’m doing the last jelq. I feel like that when the skin is held tight like that I can feel it working the inside of my penis more and stretching the skin less. I also dry jelq, which is easy when you’re uncut. I get my dick somewhat engorged, pull the foreskin all the way back, then jelq from the base up to the glans, until I start to feel the shaft skin pulling up. Unless I’m totally erect, there’s enough skin to let me jelq comfortably. And if I’m too erect, I take a break until it goes down a little.
On the huge cock thing - well there are two different things probably going on. First, guys with big penises are used to them being that way, and don’t think they look all that big. So they want just a little bit more, the same as most of us. Second, there are so many guys who are completely and totally incapable of saying how big they *really* are. Maybe they measure in a way that makes the number a bit bigger than it ought to be, or they outright fudge the data so it sounds a little better. When it comes to the internet and penis, I don’t 100% believe anyone’s claims unless they have a clear pic of their dick and a ruler, showing you just how they measured, and then you have to check that you can see the whole ruler, the whole penis, the angle of view, etc, and that it’s not photo-shopped. So yeah, don’t believe anything until you see it, and then doubt it anyways. :-)
Look through the member pics and progress reports. Not everyone is starting out big, some even had issues at the very start with jelqing, because they didn’t have enough room to maneuver, if that makes sense.
