Loss of sexual sensation

Hi,
I've been dealing with loss of sexual sensation among other symptoms recently. It is like my pain and pleasure systems are jacked. I am young and I was told I have some unfounded cause of a case of neuropathy and I have the MTHFR gene that means I don't absorb b vitamins well on my own. I sometimes get tingling in legs from time to time. The sensation dialed down a little, and I have been in contact with mold recently and got cavities done. Can Someone help? Tweet
