<s>[INST] Hi doctor, I am 31 years old and I am regular with exercise. My height is 5'8" and weight is 73 kg. My body fat percentage is 17. I used to do weight lifting. Over the last two months, I am having problem with my erection and sex drive. I am not getting that urge as I used to get before and I am not getting erections too. Occasionally when I get erection, I lose them very soon. I do not know the cause for it. I was on Omnacortil 20 for lichen planus, but stopped taking it. I am taking whey protein along with high protein diet. I have started multivitamins and Seacod tablets a month back and still having the issues. I did blood tests sometime back and everything came back normal including blood sugar. My testosterone level is around 300. Please suggest some medication. [/INST] Hi.
