Okay well here's the deal. Im 12 so my "jizz" has just started producing right. Now ive masturbated for a bit and once when I was, I hit that point when I let it all out. Its like when you get a jolt up your penis right? But nothing all came out. Is it possible to actually run out? I left the masturbating for 3 days and BAM it all came flying out. It is possible to run out of "jizz"? Is it normal?
