That file works, its scary that it does work so well at that. I was listening to kei' s file spirit girl clitty shrink (its on YouTube) for a few days and decided to do a week of no fap.
As the week went on I switched and listened to cock destroyer on about day 2-3 and started wearing panties and a good night all day to keep my dick n balls close to me. I was super aroused but fought off every erection and only got semi hard on like day 3 and 5.
On day 5 I started listening to curse of the teenie weenie. A file I've always been scared of but I was so horney by the 5 days of no fap I was blind with lust. I needed the file to work. For the first time ever my dick was actually physically retracting while I was just sitting around. I shit you not, the head was pulling back into the foreskin.
Well day 7 came around and I fapped… 7 times lol. And what started to really freak me out was that my cum was clear every time. I wasn't producing any sperm. It took a week of hard core focus and metal chanting to get over the file and my sperm came back.
Now, a lot of that is probably from the panties/ good night's. But the shrinking was so amazing. If I wasn't so worried about my balls actually dying I'd want to do it again.
