I generally Jelq straight down for a couple of reasons. It feels more cormfotable pushing away from my body, and I feel I have better control over the intesity of my grip. I also find that jelqing upwards gives me too much wood, and I have to stop jelqing to let my penis settle down. When I downward jelq I can have a session that lasts 10 minutes straight, with perfect erect level, but upward jelqing requires me to stop every 1-2 mintues.
I am wondering if anyone has experienced a similar problem, and if they used any tricks to maintain proper erect level?
