Personal jokes transfolk might giggle with me over.
My partner likes to talk about how he enjoys my topside, and I just keep reminding him that they are just misplaced testicles. (And yes, they are much bigger than his own.)
Gift notes to my partner from steam purchase.
"Ya know there's a half off sale over here waiting on ya." Signed, "Your 1/2 boyfriend"
"Want to see if mines bigger than yours?" Signed, "You know they are"
(In no way are these intended to offend, he blushes like a cherry.)
