While I always use the correct terms with my ds. I always make it clear that we must be respectful and "understand that mommy's and dad's talk about this in different ways." He nods and says "so you me and daddy talk about this kinda stuff right?" And me and my friends talk about trucks, parks and stuff" and I nod. He then says something like so__________ teaches dck about that? and I say yes....

and he walks off.
