Hi, I am having problem while having sex. My pennis is getting very less erect or hardly erect. It is not getting hard and long enough for proper penetration. I am 34 years old. For the last 2 years I was scared having sex. I am generally a very relaxed person, so I do not think I have an issue due to tension or mental pressure. I think it is a problem due to erectile dysfunction. Kindly suggest some medicine for this. I am really worried and embarrassed.
