ED after hair growth medication. Sure.

I am a 47 year old male with athletic body and good fitness, don't smoke and drink beer very rarely. I have lost my libido after taking Finastride tablets daily for 10 months or more. The effect started in 3 to 4 months but I was advised to continue with the tablets on alternate days. There was no help with hair growth but I lost my Libido and got ED. Now it has been 4+ years that I have stopped taking the tablets but my ED has stayed so can't help even if I am interested. Watching porn as well does not help gaining erection.   I have tried various known ayurvedic tablets but it has not helped. It has been really frustrating with ED. - - - - - I have read that Suhagra tablets help. Please suggest. I prefer Online Consultation if required- - - - - I have explained root cause in detail so shall appreciate a proper answer. Please don't answer in 4 words like "Get Testoterone levels checked". Pls ONLY answer (in detail) if you really care to help, are an expert, and are sure.
