I've been practicing TRE for 2 months

I want to fix my pelvic floor (hard flaccid) disorder which I believe stems from an overactive nervous system, but when I do TRE, my genitals get more numb which is depressing. Idk how to fix this and idk how often I should practice TRE because the first time I did it I felt a surge of libido and a crazy vivid sexual dream which I usually never get.

I feel stuck
