Think about it in these terms: Elves are supposed to live forever, right? Therefore they must have a great deal of control over their bodies, or we would be looking at a major population crisis. Unless, of course, sex wasn't something the Elves had on a regular basis. In which case, we can only feel very, very sorry for them.

Yes, yes, this is all speculation, and a bit silly as well, but it's a valid topic nonetheless. I mean, what's the big deal about menstruation? It's nothing dirty or scary, just part of life that more than half of this world's population has to deal with, and just because Tolkien didn't address it, doesn't mean we can't.
