I am suffering from ED. How to correct it?

Hello doctor,

I am suffering from ED and PE, low libido for the past six years. Most of the medication that helps with erection including UpHold, Caverta, Pengra with and without the combination of depressant like Prodep 10 or 20 mg (without any sign of depression) have not helped me. I have even consulted psychologists and have not received any result. There is no obvious concern found during the physical test of the penis. My current medications are L-arginine, Horny goat weed, L-theanine. My blood report indicates FSH, LH, Serotonin, and Estradiol below normal, Testosterone and Dopamine within range, Prolactin on the higher side of the range, My pituitary MRI is absolutely normal, FSH 3.03 mIU/ml (Range: 1.5 to 12.4 mIU/ml), LH 2.80 mIU/ml (Range: 1.7 to 8.6 mIU/ml), Testosterone total: 458 ng/dl (Range: 249 to 836 ng/dl), Prolactin: 10.57 mg.ml (Range 2.64 to 13.13 mg.ml), Serotonin: 250 ng/ml (Range: 70 to 270 ng/ml), Dopamine: 29.6 pg/mL (Range: 0 to 30 pg/mL).
