After I have been in your room for a few minutes, and we are done with the hellos, you say… the restroom is over there. Do I go in to the bathroom dressed, shower, and come out in a towel, leaving my clothes in the restroom. Or do I undress in the bedroom and then go into the bathroom for my shower, and then come out in my towel.

Darling, I would say just go with the flow, wherever passion brings you I personally enjoy slowy undressing a man while kissing and tasting each other. If you where with me, you would be naked before you get to the bathroom door.

Personally the "nothing but a towel" visual that is now dancing in my head is more than alright with me

Sorry to butt in on the ladies' responses. But neither scenario you described keeps your wallet secure.  

The only thing I bring to the incall is an envelope full of cash and my comb cause after she fucks me silly, I look different and need to tidy up before going home.

your straight jacket?

Just ask her to tie it back up on me so I can get back in.

Should you talk about your feelings? 
 
Your thoughts if any?

The great news is 'My shit don't stink

Your time, your dime, put your shit anyplace you want to put it & do anything you want to do.
Whatever you want to do trumps any weird ritual expectations a provider has.

The funniest thing though is when someone goes off to shower and comes back out damp but re-dressed.  
Do it however you want to do it, but don't be modest on my account .
