You should go away from these forums for a while and move on with your life. You are obviously very paranoid about having ED the rest of your life, this is exactly the reason why you don't have strong erections. Try to stop thinking about it, it's the only thing that can solve this.
Besides, most guys on propeciahelp seem to recover one way or another, since the vast majority become inactive a few weeks after signing up on the forum. There are only a handful of guys that have been active long term on propeciahelp and most of these guys have problems that are not caused by finasteride. In addition there are a bunch of hypochondriacs on that forum.
