Induced Impotence & Premature Ejaculation

In experimenting with prolonged edging, I've come up with a way to make myself unable to fuck my wife. It's very exciting because a lot of the time I want to portray myself as impotent or being a premature ejaculator.
This works without chemicals, (although I do recommend a few glasses of wine or a couple of tokes from the pipe). However, this will work even when you are totally sober.

Last night I edged for 6 and a half hours. From 10PM to 4:30AM. It takes me about 10-15 minutes to feel the glow of orgasm first begin. I will often start out stroking dry and then add drops of lube as the hours tick by. After an hour or two of edging to porn I'll get rock hard for about an hour. Slow strokes keep it hard and its this part of the exercise that feels the best and is the hardest to stop from cuming. I did let one big jet of cum accidentally escape at 2 hours, but I stopped the orgasm and waited a minute, then continued. Once you get into a rhythm, I found I was stopping myself from orgasming every 8 to 10 seconds. That's a lot of time on the edge and I continued it for another few hours. After a while my cock refused to stay hard and settles into a semi-soft state. Just a few squishy strokes brings me to the edge repeatedly and I keep the porn up while the hours slip away. After over six hours of teasing myself, my abs are really feeling it, my balls are heavy and sweaty. They tingle as they lay heavily on the chair. It takes only the tiniest of jiggles to reach orgasm, but I deny myself. I am training for tomorrow, when my wife will want to get laid and I will be unable to oblige.

When I woke this morning I couldn't get hard. Only for a few seconds did it remain at half mast and then very quickly retrated into a squishy useless penis. Now she is on her way home to me and will be expecting me to be erect and be able to fuck her for an hour. I will of course be unable to get an erection and if she persists at trying to suck or jerk me, I will almost instantly cum for her. Hopefully, she will become disgusted at me and resort to me licking her pussy and ass, while using the stunt cock (her beloved 8 inch x 2" wide dildo).

I have done this before and am concerned that there is a lasting effect of premature ejaculation that remains
for a week or more. I find it delicious and frustrating, until I really want to fuck her right, and then I can't. I have to take several days without any sex or touching to restore my quickly vanishing virility.

It is so much fun to do, and if any of you have an interesting experience with this technique, please write back what happened. Now I'm wondering what would happen if I took a Viagra (which I don't know how to get).
