I have been hobbying for a long time and I will encountered something for the first time. I will be driving several hours to see a provider in a few days and will need to take a shower before our session starts at her place. The time of the shower will not count against my time with her will it she is a top notch provider and has several pages of reviews so I am almost certain that it will not. Just wanted to get a bit of feedback. Thanks in advanced

You're gonna have to ask her.  I'm gonna assume you've seen her before since you are driving several hours to see her. Most guys wouldn't drive that far without having had a test drive first. So just ask her. If you're driving several hours why not just do an overnight if you can spring for it?
