I have to learn who Patrick Jane is. This is so interesting. But, and I am being immodest now, I also thought this. The very simple and basic thing is just comfort with body fluids. I never understood the compulsion to take a shower after the act. On the contrary, I liked cuddling together and falling asleep in an embrace (when not manic - when manic, I could not fall asleep after sex and one day after such lack of sleep I drove myself off to a parking lot and took three handfuls of tranquilizers and other crap and survived through sheer luck, thanks god) peacefully without leaving the bed.
