Stop when you reach the glans. You can give a small stretch for a second before starting the next stroke. If you’re more interested in length gains, use a lower erection level, I.e closer to 50% than 90%.
Woah, really? I normally stretch over the glans to the top of the glans. I wonder why I should stop when I reach the glans then? Any reason?
I have got stretched foreskin after what I did, so I got some looser skin at the top of my penis now which I don’t like. I wonder if that was because I jelqed over my glans or not.
Also why would I get more length gains if I jelq at a lower erection level nearer to 50% then? I wonder how that works.
