I've had some great sex with 2 Romanians, 1 still active part time and 1 looking like she'll be making a comeback of some sort from retirement. Both of them are indie so that may make a difference from all the usual pimped Roms that rack up negative after negative reviews.
I've also shagged a part Czech woman (she's a mixture of nationalities due to parents). She was fucking amazing.
The Ukrainian woman was also good but never again for other reasons I don't want to talk about.
See my reviews for more info.
As for EE I don't like. I'll have to get back to you on that one. I need to shag more of them. I can't believe I haven't had a Polish escort yet.
