It's very simple, just fill in what you are looking for. Leave the "State" blank if you are searching for a mistress NOT in the USA or Canada.

A simple search for example would be GENDER "Female" COUNTRY "United Kingdom" This would list all female (as opposed to TV/TS and Male Masters) mistresses in the UK.

You could further refine your search by typing "London" in the CITY box. Please note that this particular search box is cAsE sensitive. Therefore you may have to try, for example, "New York" then "new york" then New york" before you find every listing for that city.
