when jelqing at 100% erect how tight should i be squeezing?

the reason i ask is becaus latley ive been jelqing at 100% erect and i make incredible expansion about a half of an inch the only thing is i squeeze very tight or else i dont get any expansion , and since im squeezing so tight i endup with these little red dots all over my dick not just on my head .
so i just wanted to know if thats ok ?
and if not how tight should i be squeezing??

I suggest you back off a little. Remember, if you are fully erect, any additional expansion puts you over 100%, so you don't need to chock that bad boy like you do when it is more flaccid. I suspect that you haven't lightened up any when erect, or maybe you only it tried going easy a very few times. If you grip too tightly, there is a real chance you could burst a larger vein, or cause other problems. Try going easier for a week or so and see how everything works out. I go at it very intensely, and I jelq at all erection levels, but I have never overdone it, which has allowed my unit to recover more quickly.

why don't you try 90%?

Jelqing at 100% would require a very intense squeeze just to get an adequate stroke. It's for that reason why the erect jelq is such a risky movement. You're much better off jelqing at 80% max or less- for safety and to maximize the effectiveness of your workouts.

A good solution to this is Slow Squash Jelqs, you will start at 100% but your penis will soon give the room to do the exercise after a couple of rolls. Usually, after about a minute or 2, my erection will subside to the perfect level to do the exercise. Putting a number on it is difficult, maybe 90%?

Big Al, I don't think all of us squeeze harder when erect. The more flaccid I am, the tighter I have to grip in order to move blood up my shaft. When I am over 90%, I get a pretty good grip just getting my finger around my unit. My cs gets really hard when erect, and I am afraid to squeeze that bad boy too tightly.

DLD, just a random thought here. You always jelq at 100%, and you use the example of at 80% you need to increase stuff 20% just to get to 100. Whereas if you are at 100% already, everything is obviously 100%+ when you start. Is it possible though that when you are at any other erection level less then 100%, your cs and cc's "are use to being a certain size", but by forcing them to expand "more than they expect to", that this process will help enlarge them both at those levels and when they reach 100%? Not a very scientific thesis here, but I think you get my point.
