two points . . . .
1) If this is a provider you plan to repeat with, and she asked you not to review her, there must be a reason. Providers are usually pretty intuitive about whether you had a good time with them. The few times this happened to me early in my hobby career, I realized they didn't want to be reviewed because they had given me off-menu services. I reviewed her anyway, but limited the scope of her review to the menu items on her website. However, if this isn't the case, and she wasn't asking in order to hide misrepresentations she makes in her advertising about age, weight, etc., then I think it depends on whether you want to see her again, and if so, as Fisher says, respect her wishes.
2) As Gag says, a 5 for appearance is the kiss of death for a provider. Many guys think on a scale of 1-10, 5 is "average", but I never met a provider that felt that way. If you found her the least bit attractive, then I would recommend staying in the 7-10 range, depending on your personal tastes. Looks are subjective. One man's "fat" is another man's "sexy-curvy", but few guys want to see a girl that is a 5 in appearance, so you are effectively giving her a negative rating with a score like that, even though you say you would recommend her. Service is another matter, because the max score is determined by what menu items you actually received. This is where I have a problem with the TER reviewing rules. A girl can be the best provider I have ever seen, but if I didn't RECEIVE anal (it doesn't matter if she does it with other guys - anal is always YMMV once she sees how big the sausage is), it wasn't a doubles session or a gang bang with multiple guys, I can't give her a 10 for service. Totally unfair to petite spinners, IMO.
