The DC market is really 3-4 individual areas plus those in VA and BWI.
The DuPont Circle area as well as Foggy Bottom and Georgetown in DC are popular with touring girls though not with many locals.
No worries though.

Coming to DC/Md on business and looking for a hobby incall.  I want to stay on the DC side of the river, but there seems to be a bias for N. Virginia.  Would I be correct in assuming that I could find a good incall in DC?  Thank you.
