Could Ainur reproduce?

[Morima]

Argh Noxomanus, the mental images!! Don't even go there! (In joke. Have you peeps read OFUM at Henneth Annun?) But jokes aside, I've been wondering about that myself, really; I'm always musing on practical matters like that in stories. I think the logical thing would be, at least concerning the Wizards, that they're bound to a mortal body with all that comes with it of human instincts and such. And those are very strong in us! But I tend to doubt that they ever followed those, at least not when it comes to reproducing, and I think that's so simply because it seems logical.

I think in some Terry Pratchett-world the Wizards live in celibacy when it comes to sex, and perhaps it's like that in Tolkiens world as well. Just a thought. But it seems likely to me, considering how deeply they concentrate on other things.
