All Depends On Your Loyality......

Is it to the lady or your brother hobbyist ..  No right or wrong answer.  Just the one you feel good about.

Peace

If you write a review, then other hobbyists will expect the same services. The question is, will the extra services be available to all?
I question this because she advertises in the therapeutic section, and not the escort section. I am also assuming that you received FS, and not just a HE.

If the services are available to all, then I would write the review. If not, then I would bypass the review.

I avoid discussing reviews with providers if at all possible, but under your circumstances I would ask her if you don't have the answers regarding the services offered.

Assuming you know her concerns and she is not opposed to a review, I would tell it like it was and be clear if it was a YMMV situation. Or perhaps say to PM u for more about extras or something like that. But if u do review agaist her preference you may never see her again. I personally would assume she wants to stay UTR if she is advertising under therapeutic massage

There are some girls who advertise under therapeutic who offer extras but prefer to stay UTR.  It's hard to say if your situation is the same.
But, of course, I would like to know who it is.

If she only advertises under "therapeutic" I would not review her without asking.
It is sometimes possible for a review to have negative consequences to their personal and/or professional lives.

If she was listed in the "body rubs" section, I would say don't hesitate to review. I would think that advertising in "body rubs" carries an implicit suggestion of a minimum menu (obviously in reality that is not always the case).

If the lady didn't want stay at least somewhat UTR, she would advertise in a different category. The therapeutic massage category can sometimes have an extremely wide YMMV factor. This is a category where women who are very much YMMV tend to stay in or migrate to. A review that may generate certain types of expectations that may be unfulfilled may be unhelpful to both her and to hobbyists. I have also seen 411 threads for therapeutic ladies on here where one hobbyist will say extra is available and another says no extra. YMMV. A masseuse from this category is not going to come on this board and explain that this is the case.

Sometimes they stay in the therapeutic category because they are only willing to provide anything extra to those they feel VERY comfortable with. In other cases a woman may have decided that she only feels comfortable in providing certain services to those she actually feels attracted to. Women will have their own reasons for only providing some activities with some clients. It may be as simple as wanting to be extraordinarily certain that you are not LE. You may be SOL if she even thinks you look like you could in any way qualify to be LE. You may be SOL if you ask the wrong question or say the wrong thing. She even has to be sure not to start an HE for someone who may not want one (yes, it is possible for this to happen, I heard the story from a woman who startled the hell out of a guy once). The therapeutic ad category is NOT the same as the body rubs or escort ad categories, even though sometimes there can be overlap. Obviously, the category is also very populated with lots of strictly therapeutic-only services as well.

I've seen a woman who was so shy that she made me wear an eye pillow so that I couldn't watch her perform her "handiwork"; yet it was obvious that she was not new to the task. Even on subsequent visits she still didn't want me to watch her, despite her smiling and teasing demeanor. I am certain that only guys that she felt VERY comfortable with were eligible for the same basic upgrade I received.

When I was still pretty much a newbie, before I started seeing independent ladies, there was a parlor that I would visit. I would leave with a smile on my face. Later on, I discovered multiple reviews for the same place on a different web site. ALL of the reviews indicated that what I was experiencing was not possible. Same masseuse names, same location, same time period. At a different parlor that I felt certain would provide the same positive results for me; nothing beyond an excellent massage, even after multiple visits. YMMV

I've encountered this exact scenario.  The provider in question wanted to remain under the radar and knowing this, I have chosen to respect her wishes.  For all I know it was the chemistry that we shared that led to an experience that I never expected.  Glad it happened though...  Selfishly, I can say that my remaining silent is also because I'd love to return and recapture the moment!
