If I understand you correctly:
-  You are looking for a temporary partner for sex until you and your spouse are reunited.
-  You don't have a history in the hobby with other providers or a verification site like preferred 411.
 As such, you will 
probably have a difficult time getting a 
quality provider to see you on an out-call basis.  You are not known.  A provider needs to be assured that you are NOT LE and that you are not a nut case.
Though I don't want to cause any bad feelings with this site or any providers; I think the best solution for you is an EMP (Erotic Massage Parlor) in which the providers offer full service.  There are quite a few EMPs in the DC area that have an excellent reputation.  You can research these EMPs at...

You won't have to go through verification and a screening process.  Additionally, a 
reputable EMP will be managed by a savvy, well-experienced Mama-san the can spot and smell LE a mile away.  Hence, all you have to worry about is enjoying yourself!
I don't mean to take any business away from our lovely, independent escorts.  However, EMPs can be better choice based on certain circumstances and the particular needs or desires of a gent.
