Oh, good God, wonderful/horrible Aziraphale/Crowley sex headcanon:

So of course they pick whatever genitals they feel like using any time they make love, because they get to pick each time. No point having genitals all the time. Sometimes they rub on your clothes, and they’re distracting. Much better to just pop ‘em into existence as needed, and I suddenly have this image of Aziraphale looking up at Crowley, both of them with shirts open and trousers still on, and then a sudden pause:

“Were you thinking innie or outie?”
