Hello Doctor, I am 31 year old working in IT sector. I got married 5 months back. Initially I got my erections normally but I was not able to penetrate my wife. I have tried many times but failed to penetrate. However, for the past 1 month my libido has decreased, it seems like I lost interest in my wife. But I get normal erections while trying to masturbate. I consulted an urologist and took an injection test & tablet test. The doctor told the erections are normal and you will be able to penetrate. But even after taking the Viagra tablet once, I didn't get my erections when I was about to have the intercourse. I think something's wrong with my mind, because I have erectile dysfunction only at the thought of having sex with my wife. I am deeply disturbed by these happenings. Please advice me or prescribe any tablets.
