I'm not ready to do this quite yet.  But I plan to, once I find that special someone..er provider and chalk up the resources.  

It is reasonable that providers expect clients to be super-clean before a session, so how do you take care of those issues given all the secretions and odors that occur during the course of the night?  Do you get up and shower every few hours or just before morning activity?

Personally, I'm more concerned that she'll get annoyed by my snoring and go down the hall to where the SO ends up (after it wakes her).  Now THAT would take some explaining, hahaha.

Shower... have sex, sleep a little (*or none*) fun in a large tub, sex...  sex in the shower, sex in the tub, get dressed... leave for the Airport *LOL* isn't that an overnight? I play, sleep very little and don't sweat the small things!!! Have fun, know your providers reputation... kisses ~Tori

Just relax.  Do not even consider getting up to shower in the night, she will think you are a weirdo and you'll be disturbing her sleep!

Unless you sweat profusely during the night then just wake up in the morning and start again (rinse your mouth first).  One of the great joys of an overnight is sleepy, gentle sex first thing in the morning.  You lose that if you both shower first.  

Reon't fret about it

Can't imagine a provider thinking you are a weirdo because you want to be clean. If she got upset that you were disturbing her sleep to clean yourself, I think I would leave. Just do what makes you comfortable, You know if you stink or not!!!
