It will not effect me at all

I agree it may be upsetting for a new provider who is trying to establish herself of having a somewhat "lower score". But the scoring system is highly unreliable, some reviewers are tough graders and then sometimes ter also is known to downgrade the scores.
Your other reviewers have given you great scores, seems like the gentleman had a great time to so after reading his review I would not be discouraged in seeing you.
Now I hope you tour to Memphis, so that I can meet you.

While 7 is at the lower end of the range I'd consider, I'd want to read the review first. There is considerable grade inflation out there, so if this reviewer were consistently lower than others the 7 would bother me. I looked at your photos and you look pretty hot. Please consider visiting Stamford, CT or White Plains, NY sometime.

Since when is 7 average? Seven is good. Attractive! Hot time! From a standpoint of your other reviews being 9s, I can see you would feel that 7 is low. But some people just have higher standards. The body of the review is more important than  the number anyway, like some of the others have said. Also you said he told you he enjoyed it and wants to see you again. I would take that as a compliment. Personally when I search reviews, I look for 7 or better, then read the body of the review to see if it is someone I would like to see. Bottom line: The number will not prevent most other hobbyists from seeing you if you are their type.
