I can't speak for Koreans, but I was at a shop once got shown 4 girls choose a really cute little one and as I am a white guy it's not very obvious I am fluent in mandarin, so I guess they just feel free to talk openly and behind a thin curtain she started complaining she doesn't have sex with white guys, I was like ok this is awkward and this wasn't a cheap shop either, but she was really hot and I was already there, so I just decided to play dumb see how this goes, the boss guy came out, yelled at her and basically told her to stfu and do her job, so off the receptionist led me to the room where I waited.
When we got in she gave me the "no English" I replied in Chinese no problem I spent 6 years in China, she went bright red apologized near shit herself, asked me did I hear that I said yep, all of it, but I really didn't care as it wasn't me specific it was just Caucasians in general, I maybe wouldn't be interested in some races as when I think about it, but to your question I did ask her why come to Australia to be an escort if you don't like white males?
She said she likes white males more than Chinese males, but not as clients for two main reasons,
1. "Dick size" - I can confirm she struggled and I let her put it in really slow and didn't bang her very hard she was very appreciative, she said most guys just shove it in quick and bang the absolute crap out of her.
2. "Language" - She worries about misunderstanding people and not making them happy, then her boss yells at her and gets pissed off.....
Something I wasn't aware of aswell is she said most guys prattle on at her asking her question after question even though she has no idea what they are asking her she just says "yes" and they keep asking, she has no idea what they are asking, if I get the no English from a Korean I usually just don't talk to them, maybe some guys do, she said it's awkward as fuck.
I am pretty sure there is no prejudice, once she new I could speak Chinese she seemed very happy to have sex and she would not shut the fuck up most chinese people talk about food insistently it agitates me I wasn't paying to be agitated, she did ask at one point mid sex if I had a girlfriend when I said no, she said she could be my girlfriend and only have sex with me if she could live with me and I looked after her
, so obviously she doesn't mind white guys that much, I finished up and left quickly after that question.
