I too know that paraliminals work but the scientist in me has a thought or two.
If you had seen a physician about your ED, one of the first questions he would have asked you is if you have an erection when you wake up in the morning. If the answer is "no" then the condition is likely medical. If it is "yes" the condition is likely psychosomatic. If I understand you correctly, the answer would have been "no" and the cs paraliminal worked wonderfully - which is entirely possible.
I would also encourage you to see a physician about your condition as well, even if you've already "solved" the problem at this point. ED is often times a symptom of more serious conditions like cardiovascular disease (after all, blood is responsible) or diabetes (which often causes vascular problems).
Just my $0.02. Thanks for sharing.
