I haven't caught up to the most recent season 2 episodes, but having slow-binged (like regular binging but for parents who maybe can eke out 2 hours of TV every few days), I'm pretty sure they've shown two dongs, one pair of boobs, a handful of butts, and one baby being born. It's uncommon enough that, dork that I am, I'll say something dumb, like, "Whoa, that's a dick." (to which my spouse rolls their eyes and calls me a dork)
