It’s not an overnight thing. Since it’s comfortable stay with it a month, or four.
And, no. It won’t keep you at 60 % erect all day, either.
But it does hold some engorgement longer than if you didn’t use it or some other cock/ball strap. And there is a certain sensual element, too, to having it on. You get a “stir” at some point during the time you have it on? that stir will last somewhat longer on you.
The point of using it is to have some constriction but not to the point of interferring with blood flow both in and out of the penis and the testicles. Frankly, because of the way the device is made and the way you apply it, it seems really difficult to make the wrap too tight. But as peforeal has said, you can go for a bulge, or an “obscene bulge,” depending on how tightly you wrap.
A couple tips: As soon as you finish your PE workout, put the wrap on. You can be completely erect at that point, or just sort of pumped-up. Wear it for a couple of hours. At the least, you’ll stay a bit more turgid and heal some of your micro-tears in a somewhat larger state than completely flaccid.
I wake up with morning wood almost always. I’ve got into the habit of “catching” those erections as soon as I get out of bed by putting on the wrist band then. I do my PE routine an hour or so later in the morning, take it off for that, and put the band back on after I finish with PE. I’ve got so used to it that I’ve gone for as long as eight hours with it on, pretty much forgetting that it’s there. But I’m self-employed and work at home. If I still had to go to an office regularly, I’m sure I’d be a lot more self-conscious about using it. With it, you do have a noticeable bulge, no matter what kind of pants you have on.
As I’ve already said, I can’t account in any other way for my own flaccid growth spurt. I had already gained most of my erect size when I started this practice. It just seems to have done the trick to get my flaccid size to catch up with all that erect gain.
