Difficulties with Jelqing due to smaller glans

I just started out with PE 3 weeks ago, and I’m still learning how to jelq properly. Because my glans is smaller than the middle part and I am uncut, sometimes while stroking forward, I push the skin forward but the erectile tissue snaps back into the body. It’s kind of hard to explain, but imagine like you squeeze a bag of Popsicle on the bottom so it gets out on the top. So it’s somewhat difficult for me to do the steady, slow forward stroking like in the tutorial video: Wet Jelq Video

I’m not sure whether this will affect the PE. Any advice?

You could try to use a tighter grip. Maybe make sure it is plumper than what you are working with now. And when you dó reach the glans ridge it is actually better to not go over it. Or so I have read and been advised to. Also doesnt feel good.

Glans shouldn’t have any kind of participation on jelqing and the stroke has to stop before you reach it.

Are you jelqing fully erect?
What grip are you using?
