Escorts see too many guys to be concerned about looks. If you are friendly, considerate and CLEAN an escort will enjoy your company and give you the best time possible because she will want you back as a regular. If you are dirty and inconsiderate you could look like Brad Pitt and the escort will still try to get rid of you as quick as she can.
The way I look at it, money gets you in the door. How good a time you have is as much up to you and your attitude as it is the escort.
I have to say, as one who has passed close inspection by Kat, that I was very disappointed not to come away with a Certificate of Cleanliness.
