The reason why we do 28 days is to rewire the neurological pathways of the brain for orgasm and pleasure. When you have been doing the same thing over and over for years, you hardwire your brain for this.
This includes watching porn, masturbation, ejaculating every time you masturbate or have sex, initiating sex and being rejected by a partner, or even not being sexual enough and having your sexual energy shut down.
Like any habit, you have to spend a chunk of time away from doing things the old way and bringing in new ways of doing things to rewire the neurological pathways of the brain. I will give you all the new tools, exercises and practices to do this over the 28 days.
