There's a lot of information there! I will not pretend to have had the time to digest it all but an initial reaction, if the article is stating there is perhaps a high degree of narcissism amongst crossdressers, would be really! tell me something I don't know!
I do not however think there is anything abnormal or 'wrong' about this. I certainly do not think it is exclusive to crossdressers. I know plenty of GGs and males who like the sight of themselves in a mirror. Additionally is there not also a psychological theory that males and females often choose partners who have varying degrees of physical resemblance to themselves..
