joe, this is a long shot and i am no doctor, but i wonder if your extreme cutting resulted in extreme deficiencies in vital minerals and vitamins, which could cause a breakdown in your nervous functions such as feeling, the libido and endocrine system.
if you have not already done so then attempt to rectify this by taking a full spectrum of minerals and vitamins as supplements for a few weeks. take highish doses but obviously not high enough to be toxic or to overload the liver. google everything, check dosage ranges.
this means the lot....zinc, copper, boron, selenium, chromium....vitamin d, all vitamin b’s...calcium...magnesium....etc etc...the a to z. take at the right time of the day and not all at once, do some reading about timing, whether on an empty stomach or with meals etc.
this might seem too obvious and a long time ago i would have assumed doctors would have already suggested it, but over the years i have lost a lot of confidence in the medical profession and they may not have done so.
