However, I have been having a problem with my ED for the past six months.When I am in the mood for sex, I get ED problems. Sometimes my penis gets hard and then it goes away after a minute. This happens to me sometimes, but it is not regular.I had also shown it to my cardiac doctor and my general physician, who is a doctor, and he had also shown it to me. He had given me a tablet to take for a month, but I had taken that tablet twice because I was having side effects. I had taken that medicine after asking the doctor in my cardiology.
