I like the massage girls on backpage.  There are two or three agencies with them.  Girls change frequently but you will get your fill of young polish and Ukrainian girls.   It's not full service though.  Search massage and you will find the reviews.

If you want full service look up Elsa and Annetta.  They are part of an agency that is very easy to deal with and very accommodating.  They are polish.  They have others I believe as well.  They all have good reviews on here.

I have not gone to Polish Princess yet but I understand that they are awesome to work with as well.  

Then there are the independents on backpage escort page.  These are my favorite but are hit or miss and wildly unreliable.  They can also be cold and not gfe at all.  I have a weakness for them and there's not much I can do about it.  Good luck.

Just like a regular handle. It's no different.
