PFS throws you for such a mind fuck that you become paralyzed with fear about making yourself worse off.....if that's even possible for some guys.
There is also two different components of the issue. The neurological ones, where in my opinion cause most of the issues. And then the physical ones which include hormones, etc. You can have your hormones perfect with PFS and not have shit for a libido. You also don't feel alpha, confident, etc. There is strong evidence of Gaba system impairment which would explain most of this.
