Question What to expect in a body slide

[Pwatson]

Questions from a person who has never been yet to a spa, so please forgive my ignorance.

1) When you book 30 minutes for a room, is that 30 with the provider or do you have to fit undressing, time with the provider, shower, and dressing all in the 30 minutes, so maybe 15 to 20 with the provider?
2) In body slide, should I expect the slide to continue to the final release, or is the release not normally included?
3) Is body slide usually face to face or boobs to back? Would I be expected to wear a condom or squirt between our rubbing bodies?
4) What is considered allowable in terms of touching the provider and is mouth to breast usually permitted as part of the session?

I realize that each provider and situation may be different, but don't want to go into my first session completely ignorant of what is normal. Thanks for any guidance available.

Any recommendations for a girl good with first timers, particularly older gentlemen is also appreciated. Living in the Mississauga area near Square 1.
