Does anybody know if TRT improves penile sensitivity? My sensitivity has gone way down after I was forced off HCG monotherapy earlier this Spring. So far the sensitivity has not returned on TRT. I just started adding HCG to my protocol again, but I'm only two shots in. What causes the loss in penis sensitivity? I don't have diabetes, high cholesterol or blood pressure. I realize libido is a complex thing, but I'm holding out hope that somehow that will re-emerge, but for now is there anything I can take that will improve sensitivity? Do ED medicines help with that?
