As a parting thought, I'd just like to say that life has changed quite a bit since boy was boy and girl was girl. Look at Trump allowing a woman that was actually born a male enter a women's beauty pageant, because even though he was a boy, he's now a girl, making her a she instead of a he? So as you can see, clearly spelling out the differences between men and women is getting a bit more difficult these days. I wouldn't stress over it too much. ;-)
