<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, just wondering how a person without ED would respond to Cialis: Would the erections be harderlonger? Im asking this because I have ED and Cialis is helping me a lot and Im just wondering if this is a proof of me having some kind of physical problem and that its not due to any psychological factor.. What do you think?  <response>: Hi, If you are real having ED then Calls is good medicine. But please assure that you dont have any heart disease, stroke in the past, or any visual problems in eyes. Because Calls is nitrate group medicine ant it aggravates all above conditions. Calls do have powerful effect on your penis. It makes hard and longer erection. Though It is not good for long term use. I suggest consulting psychologist for getting alternative medicine. Take care. Hope I have answered your question. Let me know if I can assist you further.
