what? He's only 4!

my husband just told me that our 4yo (5yo this Monday) asked why mommies and daddies sleep in the same bed with no underwear on.. he's never seen us together in bed, so this comes at a shock for me. he said he told him, because sometimes they want to cause it's comfortable. any better answer? I believe he's too young still for the sex talk... just not sure what to say if he asks again..
