Hello and welcome to Healthcare Magic. Thanks for your query. I understand that you are quite distressed about your sexual problem. From the description of your symptom, it appears that you seem to be suffering from low sex drive and premature ejaculation. It is possible that hypothyroidism or certain medication used for its treatment can be one of the causes for sexual problems like low sex drive. However, other medical problems like diabetes, hypertension, hormonal imbalances, etc. can also cause sexual problems. Psychological factors like stress, anxiety, depression, etc. can also play a role. So, I would suggest that you see a psychiatrist or sexologist for a need a detailed evaluation and further management. Regards, Dr. Jonas Sundarakumar Consultant Psychiatrist
