Loss of sexual sensation

Hi,

I have decreased pleasure sensation during sex, my pain sensors are off to. I have ATP metabolism issues and MTHFR gene that effects b vitamins and found out I have neuropathy but no cause for it. I wanted to understand your feedback, because I'm not sure if this is nerves.
I've been taking supplements to help with energy and b12 but see a little improvement but I was wondering can these problems be reversed. Tweet
