I've worked with this file in the past, but it didn't seem to be working, so I got disappointed and gave up on it. However, while I was browsing some nipple sensitivity files, some users reported that the files seemed more effective when they played with their nipples on a semi-regular basis seemed to notice the changes of their files becoming noticeable more quickly than when they didn't play with their nipples.
SO, with a little pseudo-scientific speculation on my part, believing that interacting with you body in the way that you would once the file is in full effect, I tried masturbating more often, like multiple times a day, hoping that my body would get used to producing constantly. I gave up eventually, but maybe I'll revisit the file later. This may or may not be the answer for you, but there's not a lot of feedback on this file that would allow me to make any sort of guesses like that "scientifically".
