I just saw 20/20 interviewing Norah Vincent and those she interacted with and all about her book "Self Made Man
". She became "Ned" for 18 months and tried to become one of the guys (note that she's a lesbian). To a large extent she did: good enough to be accepted by other men as one of them. And she had some interesting perspectives on men: we face more stress in many ways and need to be able to share more openly, "intimately" but lack the languages (protocols?) to do so.
The interview was interesting enough to add to my list of books to buy. (grin)
Update: Reviews at Amazon.com are interesting, esp. from a "man" (who had a sex change from female to male). Still seemed like a good book....
