After that today I saw very little blood coming out of my penis whole.. Nothing hurt or anything, is this very bad should I go to the doctor or just rest it? No pain no nothing just the smallest tear of blood came out.
That’s a pretty normal injury from jelquing. You’ve likely made a small tear in your urethra. If you stop jelquing and leave it alone it will heal in a few days. It should heal very quickly, though you might want to give it an extra couple of days to make sure since this is your first time.
Most of the penis is quite tough, and you could probably tow a car with the tunica. But the urethra isn’t strong. It has been described as "having the strength of wet toilet paper", which is an exaggeration, but it’s still quite weak by comparison to the amount of pull you can apply to it with your hand.
The urethra will stretch and grow like the rest of your shaft. You might try to adjust your grip where the tips of your fingers aren’t riding along it as you jelq. That sort of depends on your girth and the lengths of your fingers and palm, though.
So, take a short break, then restart with a bit less effort than you were using before, and work back up more slowly.
