question: Hi Doctor, I am 29 and facing no health problems. My only problem is that I am not getting hard erection. I dont smoke, no alchol, I am unmarried. I had GF in my past and I was gud on bed. But from the last 18 months or so, I am feeling the difference in  my erection. I do not get excitment while watching porn as well. I feel lack of intrest in sex. Please advice as it is affecting my mind.. I will be getting married in few months... and Its a arrange marriage... Please advice if I can have good sexual life..Thanks
