This is a strange one. During sex and oral I've found most good British escorts want it rough and seem to enjoy it.
However after the act when they see their hair they seem to go into a right bad mood.
Yep, had exactly this experience with both British WGs and civvies, with requests to go rougher, or humiliate - and then generally silent treatment afterwards when they see their hair or makeup messed up, often rinse and repeat the following visit.
Also had a few EE girls who liked slightly rougher sex - generally of the 'fuck me harder'/'fuck my face' line though, rather than any kind of role play.
I think that's probably a cultural thing though - I remember discussing porn once with a Hungarian girl who said she didn't understand why some porn featured things like dildos and vegetables ('can't he just fuck her hard with his cock?').
