Since a couple of days I have trouble to get an 100% erection. I do 5 days a week 5min warm up 10min jelg and 4 hours stretch with the sizegentics device. I began the first of this month. So I don’t know if I do anything wrong? Or is it the device? And also if I do the jelg with my fingers on top and my thumb down, I feel the blood go tru my penis. And with my thumb down I do not feel anything. Is this normal?
