Is there anything unnatural about a woman in her early 20s being attracted to a 16 year old boy, a man in his 20s being attracted to a 16 y.o. girl?

Yes, very much so. It's creepy. As a 21 yo myself, I can't even [i]think[/i] of dating people below 19 without being filled with disgust. The difference in experience is so monumental that they basically seem like kids. 16 year olds are [b] actually [/b] kids
