I have a question about incall rates.  I'm new to this and still trying to understand it all.  When going to a massage parlor or a modeling studio are the rates by the hour or by the services?  I don't want a GFE, only touching and a bj.

If you find the right provider you get what you are looking for at the rates that brought you to her. The dynamic changes only if you ask for specials that good ladies provide at extra charge, such as Greek. Avoid upsellers that advertise a low price then attempt to get all your money once the little head is doing your thinking.
Your needs sound simple. Examine reviews using the two criteria that you have. There are many ladies to select from.
