Good morning.
"Furthermore, I would think that many primitive people, up to modern times, thought nothing of sexual activity with pre-adolescent females."

I'm just guessing, but I would bet that the smells associated with menstruation would generally make the female "available". That's not to say that there aren't deviants among all human groups.

Well now! That's quite a balloon floating by. We are talking about fairly recent humans. What's your evidence that they were prompted more by their noses (now a very poor source of information) than by their eyes, as they certainly are today? Eyes, and of course opportunity.
As for menstruating women being available rather than the opposite, and perhaps also downright frightening to primitive man, we needn't even go there. I'll presume you meant sexually mature women at any point in a cycle. Still, I believe she'd have smelled like whatever she was wearing. Flowers. Leather. Ideally, fur. :)
