Monkeydude, at first I thought I could only do jelqs with porn, to keep my partial erection; but after trying a few times I learned to push blood into my unit with kegels, and you can push the blood down with two or three successive pulses and fill it up. After a few jelqs and opening up the capillaries the unit seems to open up to the blood flow. I recommend practice your kegels and jelqs, because they are the mainstay for most PE programs.

Also are you warming up sufficiently? No use trying to get blood going through a cold unit.
