Summary:

They’d put so much thought into Dean’s mixed feelings about his secondary gender, but when the first signs of trouble appeared, they came from a completely different direction. As it turns out, biology-related baggage isn’t limited to one end of the spectrum.

(Or: Cas’s rut is approaching, for the first time since they mated.)

Everyone who asked about heat/rut sex in the Grown-Up Choices verse: here it is. (Well, starts.)
