Your FT is being decimated by your high SHBG.
Your Estradiol is too low.
Sorry to disagree, buy my NON medical opinion says that your HORMONES ARE the reason for dead libido. You need to LOWER SHBG and raise ESTRADIOL.
In my personal situation, I have insanely high SHBG and had almost undetectable Estradiol, which is not normal. I needed danazol to lower SHBG (although proviron might work for you).
Everyone here will tell you to get on TRT to reduce SHBG. I suggest you try to reduce it before getting on TRT. That gives you two opinions.
Here is my story.
