Head of the penis stuck in the cylinder

[vernus]

Someone who practices pumping penis could help me in the problem that I have when I make pumping penis.
After about six minutes of pumping the head of my dick gets stuck in the cylinder. Even applying too much lubricant I can not get no stretching and thickening. Only the head of the penis is stuck the rest of the body does not fill the cylinder. I did not apply much pressure and do not jelk with the cylinder. Why does this happen?

What does your girth measure? and what does your head measure?

It sounds like you need a wider cylinder. My entire shlong fills my penomet tube girth-wise after I've been pumping for a while, but I have never gotten my head stuck in any tube, be it a water or air pump. Your cylinder may be too small for your girth.

If you have a huge mushroom head and a narrower shaft you may want to wrap you glans to keep the swelling down.

The body of the penis girth 4.9 inch (12.50 cm) and the head of the penis is slightly thicker 5.3 inch (13.70 cm)

Do you know what size your pump cylinder is Vernus? And is the tube straight, or is it bigger at the opening than near the other end? I am thinking it may be an issue with your cylinder not being able to accommodate your dimensions.

I have short and thin penis. I do not think the head of my penis is big. Length 5.8 inch (14.8 cm) NBPE. The body of the penis girth 4.9 inch (12.50 cm) and the head of the penis is slightly thicker 5.3 inch (13.70 cm). I would like to thicken my dick at least 1 inch. How could I engage the head of the penis not to swell?

You should be using a 2 inch cylinder.
