I got all the info from the PE manual Big Al wrote.
As I understood it, mini jelqs are for the glans of your penis. It is to increase the size of the glans.
I watched the video how to do it. Basicly you hold your penis with the OK sign with 1 hand. With the other hand you (mini)jelq from where your grip ends till you hit your glans. I do this about 10 times while making sure that blood is pushed to the glans (kegel between mini jelq). After 10 times you tighten your grip. I didn't see this in the video but I also slowly move the tight grip upwards.
Blood is pushed into the glans, more then usual this causes the blood vessels to expend and (if all goes well) should increase size of the glans. I do this because I don't want my glans to get out of proportion in a year or 2 when my girth has increased and my glans hasn't (let's hope it increases
).
The squeeze, also from the video section.
When erect, take a tight grip with the ok sign right under your glans and a tight grip at the point where your penis comes out of your body. Squeeze both right at the same time and hold for about 10 sec. I do this 5 time as it is quite intense. You can actually see your blood vessels pop out when you do this.
My guess is that because there is pressure from both sides, blood will be captured between your grips. This causes stress on the tissue and causes micro tears in the tissue.
Big Al please back me up on this.
I'm still a noobie and still trying to figure out how to do all the exorcizes correctly and which exorcizes are good for me.
Cheers!
