I cannot comment on how realistically male they feel to men, Ged and Will Stanton both *felt* like complex and interesting male characters.
I can (to one man, at least) and I agree. So here's a question: if Cooper or le Guin were to change those characters to female, what would they have to change about their actions or characterisation to make that convincing?
I think the obsessive his-skin-smells-amazing phase is hard to write well
It probably only works when it triggers a strong memory of the reader's own experience.
