Erection level when clamping
According to the instructions, one should obtain a full (100%) erection when clamping. However, I have found that, at such level of erection, my penis is too stiff for it to have any kind of expansion.
I have tried clamping at around 85%~90% erection and the results seemed to be better than at 100%. It engorged more and the veins popped out more and I could feel that the unit was being “worked” harder.
Did anyone else notice that, too, or am I doing something wrong here?
