I've also noticed that Indian WGs tend not to offer OWO. Which is a shame, as (a) I like it and (b) I find slim Indian ladies a real turn on.
There used to be a cracking Indian WG on AW, under the name of HotStuffxxx, that worked Coventry/Birmingham areas. Saw her 4 or 5 times, and she was up for almost anything inc anal, and then disappeared. Told me she was at uni, and the escorting helped her funding, but to just stop like that....
Been nothing as good or as willing since.
