Trouble Holding 40-50 erection

I am still uncertain on whether or not my penis is just flaccid but with alot of blood left over in it or it is really just 40-50% erect.

I also have trouble maintaining this level of erection usually after 20 jelqs or so. Does stopping to readjust your erection level ie.. Masturbating a little bit to get it back up repetitively a normal occurrence when jelqing? Will doing this prevent gains or lead to a uneven pressure such as a baseball shaped penis

A lot of guys have this problem when they first start PE. It usually gets better as you get used to the exercises.

I do my jelqs in sets of 30.

30 jelqs, masturbate to bring erection level up

Rinse and repeat.

I do not believe it has hindered me. Who knows, it may have even helped. I am a “firm” believer in frequent daily erections — they are good for your penis, they probably help cement gains.

I find the technique here helpful: Clamping Jelq Technique. Maybe you will too.

Have you tried dry Jelqing? I find it way easier to keep it big and large. I actually feel comfortable dry Jelqing at a full erection.
