This information corresponds to my LOTR fanfictions. Most of it hasn’t actually come from the original books. But that’s called creative license. ;)
*Elves in all rights care very little about the appearance of their own bodies and find unnecessary the shame
that men bear. Nudity is perfectly acceptable and even new acquaintances will undress in front of one
another. This is not to say elves are promiscuous and will sleep with just anyone, but they do not worry
about the same things as man, and are more free and casual lovers, building into strong relationships or
winding down to just a comforting friend.
*Only the barest patches of body hair resides on an elf, more modeled after a human female. Elves will never
grow facial hair unless they renounce their immortality, even then it is naught more than a mild mustache or
small goatee. Most body hair is soft and thin, matching the color of the elves’ scalp hair and eyebrows, never
more than half an inch in length.
*Elves have a control over their body no creature can match. They can hold a position for hours on end, no
matter what the pose or how much strain it puts on the body.
*Elves have an amazing supply of energy and stamina, allowing many experiences to be heightened and also
repeated far beyond the capacity of humans.
*Each elf holds a small amount of magical ability, usually manifesting itself as energy. Some can use this to
heal, others telepathy, and some can manipulate the energy in other ways. No one knows how many
different variations of this energy occurs in elves since the variations have never been recorded, and few
elves will boast them.
*Elves can sleep with their eyes open, mixing dream with their surroundings. Occasionally they will fall into a
deep sleep and close their eyes however, if exhausted enough or they pass out.
*Elves have a large lung capacity, double perhaps even triple that of an average human being.
