When you can't even find porn sexually exciting/arousing, is part of you dead inside? 8-)
Feels that way nearly every time I have inspiration enough to try and should I maintain the inspiration long enough, the end result usually doesn't feel pleasurable.
If I was in a real life situation where I though sexual excitement/arousal was going to possible I would probably have a massive panic attack and do everything I could to escape/flee to 'safety'.
