Voyeur,s sub New ED confession about cumming

Dear Headmaster,

I have sent you a video as a proof that my ED has got to the point that even during masturbation I cannot get fully erect.
I planned to do this video since a while to show you and everyone who follows my xhamster page how ED sissies masturbate. During preparation for the video, I freshly clean shaved my balls and mancunt. As usual I had no erection at all, so I put a tight rubber band around the base of my penis, my balls and the base of the penis shaft to force some blood in my penis. It got semi-erect, that's when I started shooting the video. Since I haven't had an ejaculation since about two weeks I cummed quite quickly as you can see, it only took about 5 minutes. I took of the rubber band mid-time to show that even while masturbating and getting close to the ejaculation, my penis doesn't get fully erect. After continuing to pull the foreskin on my cock for another 1-2 minutes I felt the ejaculation to build up which finally happened.
There was one not very strong shot, the rest of my sperm just kind of flowed out of my penis, this is as it usually happens, no multiple strong sperm shots as potent real men have. To finish off the presentation I rubbed the sperm at the end on my shaved balls and anus and tasted my beta sperm on camera.
