Interesting thread! I have had a higher % of bad punts with Roms, but i've also had a few great punts too. That slender gypsy/mixed Indian or Latina with a booty totally floats my boat, but the attitude I get from most is a nonchalant frozen fish. Might be down to my own attitude and the way I approach a punt.
It really depends on my mood and attitude in the moment...when I've wanted a more intimate gfe, dfk + long fuck session with a Rom girl, it usually turns to shit (mostly likely they just don't do that fluffy gfe stuff!). When all i've wanted is a quickie pump and dump looking at a great ass or tits, these Rom girls seem to take a cold wham bam thank you ma'am punter well.
For e.g: I was out and about one night, feel super horny, and not in the mood for bullshit. I booked this Rom girl. It was risky, her place was a shit hole in a dodgy area of London. BUT she was hot as fuck with a great ass, aaaaand she had a stanky attitude. Once in the room and rubbered up, I just bent her over and banged her hard for 15 mins until I was spent. I felt great afterwards! Another Rom lady, i was completely taken by her good looks, just stunning and I could not alpha male it. I turned into a coy shy boy. wtf? Her attitude was like, well boy I don't find you that hot, you either fuck me like a real man or I'm just gonna lay here like a stonefish until you dribble. lol
Other EE WG's types - Polish girls have always been more passionate for me, better at a gfe service. I remember seeing this Polish girl, quite a few years back. All we did for the hour was dfk and play with each other - like making out with a proper girlfriend and with passion. I'd pay her for an hour, but she'd stay for 90mins - 2hours without charging me extra AND we'd fuck each other's brains out have a laugh and a good chat too.
Lots of other Polish ladies I found were great too! It's hard to find a WG like that nowadays who just goes with the flow and isn't a clockwatcher. I'm sure there are some but as always, YMMV.
Very broad brush, but that's my personal experience.
edit reason: grammar.
