I began my routine by warming up my penis with hot water for 5 minutes. I then did manual stretches for 5 minutes as well. I started jelqing and I felt and sharp pain on the head of my penis. It felt like it was a sharp pain coming from the urethra. I immediately stopped because I didn’t want to risk injury. It feels fine when I don’t jelq. Should I try again tomorrow night and see if the pain is present? If I get pain again tomorrow what would be wrong? An injury perhaps?
