Because it's only make believe

Good Omens. Crowley and Aziraphale pose as husbands for a house party, because Aziraphale is bad at saying no (to anyone but Crowley and anyone trying to buy books).

Crowley thinks this is a good chance to prove himself the perfect potential demon husband to a fussy angel. But things get complicated fast. Really complicated.

A lot of pining, a lot of shopping and restaurants and party games, some near misses, but no sex until chapter 24 (and all of 25).
