And I feel like you’re really going out of your way to sanitize it after the fact.

I think you are making too much of a connection between the sexy part with the sleeping part instead of the sleeping in while sexy and going to work part. Sure, it could have been changed to just sleeping or just sexy without the obviously exaggerated for comedic effect phrasing but then it would have been a tame and less effective joke.

Seeing a sleeping partner cozy under blankets and not going to work is wholesome. Seeing a sexy partner and not going to work, but with a tame description of the sexiness is tame and not funny. Seeing a sexy partner who doesn’t have to get up while you do AND an exaggerated description of being sexy with a ridiculous phrasing to emphasize that they would rather be having sexy time with their partner than go to work is funny.

The exaggeration is the joke and wouldn’t be as funny if it was tamed down.
