I try to be mindful of cuddler's time so my communcation before the session is usually about logistics unless they're up for some banter.
I usually ask:
Cologne yes/no
What kind of temp do you like?
And remind them I have a cat
I of course watch sheets, pillow cases, blankets. I have coconut water on hand for them.
What do you do when preparing to host. Would like more ideas
