Numb Penis after injection

Keep in mind that you are experiencing non-physiological variations in serum testosterone with these weekly injections. The peak levels after an injection can be 2-3 times higher than pre-injection troughs. To see if this is contributing to your problem you could try switching to 20 mg TC three times a week. It's also possible, as @FunkOdyssey says, that HPTA suppression is a contributing factor.
You need to check ferritin on TRT. My ferritin levels decline very fast on TRT and require a heavy dose of iron! If I stop TRT, I no longer need iron supplements.

If your ferritin did take a hit on TRT, stopping would allow it to recover and you'd never know.

Why did you start TRT in the first place, because you were told to start TRT based solely on the numbers or because you had symptoms of low-T?

My ferritin on TRT was 89 (Range 30-400)

I gave him a plausible explanation for what’s causing his issues. It’s as if it was completely dismissed.

He wants the easy answer, the quick fix. He’s not going to be able to figure this out without some trial and error.

We aren't answering you because we don't know. Fortunately, you don't always need to understand the exact mechanisms at play to troubleshoot TRT problems. Trial and error is the way.

P. S. Don't forget about hCG's reputation for restoring sensitivity in men on TRT. I will keep repeating this until you acknowledge you've heard and understood.

Thank you very much! I did not know that about hCG. I really did not want to start taking something else to fix the problem. I really thought I could adjust the testosterone dose amount or dosing frequency to alleviate the issue.

You may very well be able to make an adjustment to the TRT and fix it. If you can't though, I just hope you don't give up on TRT before trying hCG.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
