Yeah those bastards are damn hard!! Had some workouts that would only last 20 min because of these guys. It's all about listening to you member. If it tells you to slow down, and that you should wait, then stick to the Uli's nd squeezes. You can always go back, when you need something a bit harder!
Although this may sound kind of strange, but once I started doing the Low Erection Jelqs again my damn EQ is rock fucking hard again, and that EQ seemed to diminish when I was doing those High Erection Squeezes directly followed by Jelqs.. It was like my dick had a hard time keeping the blood in it's chambers. Damn that was close to fatal cock lol now it's time for some gains~!
