hard one when jelqing

Do I need to have hard one while jelqing? I use to make my penis erect to 70% then I start to jelqing. But after some time I loose my erection. But I still got the blod to press, as my penis head is really large.

70% is perfect for a standard jelq. If you are having problems maintaining this desity some porn may be your best bet. What presure are you training at when this happens?

happend both medium and hard presure…

If you think you are going to loose your erection, masturbate a little bit, get the blood flowing again. Work great for me

I understand your problem well.

At first I had problems because i got too hard from jelqing and the session ended very shortly, if you get what I mean.

However I started with a pay-site which recommended 100% erect jelqs, so I continued trying.

Generally, the more the erection the better for girth, with less erection better for length. This seemed to be my case too because I got girth gains from my erect jelqing - although now looking back and in hindsight I would warn anyone starting from this as too much pressure can cause injury.

And it is very normal in the second-third week (or later) to have problems with maintaining or even getting a rock hard erection. But this is also temporary.
