Using extender, think I might have gotten my first injury

So after using the extender a bit yesterday, and doing some manual pulling I think I got my first injury as a result of PE. I found a somewhat small purple mark, most likely a bruise caused by a popped blood vessel almost at the base of the penis. It does not hurt at all actually, so I was thinking about not taking any breaks, should I? I consider my penis pretty well conditioned cause I have jelqed at high erection for a long while and had no troubles with uli’s. I just think it is at such a weird placement. Also woke up with a raging hard-on which made me somewhat happy considering I had not used my extender for a long while and I felt it affected my EQ instantaneously.
