I'm not sure why psychnet-uk.com put such a misleading preface to its article: I think they were trying to avoid stigmatising people with a "disorder" in cases where it's not causing them or their partner any distress, but they worded it remarkably badly if so. However, the crap bit isn't actually part of DSM-IV.
