Why would one charge the same high rate if the guy only wants a bj or a massage?

How about ... because they can.

2 different areas.
There are guys who don't wish to fuck and are comfortable with just paying for a good rub down and release. Originally Posted by RandomBlkChick

In my opinion, if you'd like to get a bodyrub, call a bodyrub girl. If you'd like the Full Monty, call a full service companion. But there are some ladies that can go from bodyrub to GFE to PSE to KINK in 0.2 seconds, and there will either be one rate, or rates per service. As long as you can afford what you want, there shouldn't be a problem.

Sometimes you find a certain full service gal very hottt but truly only want a bodyrub. Often the choice of the gal is more important than anything else. Bodyrub clients will often try to push bodyrub gals for more but guys just looking for a bodyrub from a certain full service gal just want to be with her and fully accept just the body rub. As stated, full service gals should handle these requests in whatever way they desire and the guy should accept that.
