I'll admit it is kind of hard to tell anyone's gender if they have a non-gender-specific name.

And even if the name is definitely male, you can't always tell... Finwë and Fëanor of the Peredhil are both female, and there is a female Samwise too... The avatars are often misleading as well!
But I think there are no male Downers with female names!
Anyhow, even if I'm curious, I would feel a bit awkward asking "Excuse me, are you a he or a she?"
