What Tolkien Officially Said About Elf Sex
"To disappoint slash writers everywhere, there were no clear statements of elf homosexuality. There weren’t even any unclear ones. The most suggestive elf/elf pair are Fingon and Maedhros, rescuing each other and sending each other presents just because. ... But even they have less eyebrow-raising stuff going on in 500 years than Sam and Frodo managed to pack into one day."
(But calm down, o traditionalists: this author says on a different page that Tolkien did not intend Frodo and Sam to be gay at all.)
