There's one of Tolkien's notes that implies that elves could and would die in preference to being raped: > But among all these evils there is no record of any among the Elves that took another's spouse by force; for this was wholly against their nature, and one so forced would have rejected bodily life and passed to Mandos. So I think this raises some doubts about whether Tolkien intended to imply rape in Celebrian's case rather than some other evil.
