Thanks for posting, haphazard and imLIN. I am finding it very therapeutic to write my thoughts down here.
Re ED and heart disease: my uncle died suddenly of a heart attack at about age 60. He was thin and a very heavy smoker who once said he'd rather smoke than eat. I found out a few years ago that he had ED and had been on Viagra shortly before his death. There wasn't a family history of heart disease that I know of. Scary.
