HA! This thread is great. I'm going strong boys, and I hope you all are too! Another thing that can cause erectile disfunction is some sort mental uneasiness. I went through a 3 week period of temporary ED due to a serious blow to my self esteem/confidence, partially due to this heart thing. This was actually pre surgery. I was all worried, but once I got my head straight, everything went back to normal. "the erection takes place in the brain" is something I came across allot in my research. Moral of the story: stay healthy both physically and mentally and heart surgery should not affect your performance.
