Does your penis erection level change during exercise?

Does your penis erection level change during penis exercise? Or does it stay consistent? What are your guys tips for making it consistent

It changes. Specially while jelqing

My challenge is maintaining EQ during jelqing (as opposed to becoming too erect). Ideally I would stay around 80% erect but I often fall to 40% and work my way back up.

One promising thing I am finding is that as the jelqing hand motions and flow have become more second nature I am now able to devote less focus on my hands and devote more focus to imagination in order to maintain 80%. I often switch my focus back and forth between what my hands are doing and what I’m imagining to stay turned on. It’s a delicate science and obviously you want to stay present with your hands so that you don’t injure yourself.
