Ooh la la, Lúthien...

[Lush]

A very...interesting topic.

It's a dirty job, but somebody has to start these topics.

Here is what I can add to the discussion so far: Celegorm is a great example of an Elf that was definitely not above lust. He was the illustrius dude that kept Lúthien captive, and wanted to marry her against her will, and against Elvish custom, as I recall.

And relating marriage to the Fellowship is an intersting and, I think, relevant way of thinking about this.
