If you are doing a hard mode reboot then no, you shouldnt masturbate. if youre jerking off without the aid of any images or any artificial stimuli, then it might be ok as long as you dont overdo it. in my experience, having a wank hlped me to get out of a flatline several times. the important thing is not to force it, though. some guys get a little worried about whether or not their cock still works so they jack off before their body is ready and it can do more harm than good. if you want to jerk it, fine, just be sensible about it. everyone reacts differently to these things.
