I feel like the opposite is true re: Asians vs. Western(American). I've never had direct experience with Caucasian girls, but growing up in NYC, attending a Catholic elementary school, I witnessed a lot of sexual innuendo and suggestive acts with the white kids, who were mostly Italian. And these were pre-teens. Being Asian myself, I can promise you that they didn't even joke about sex, much less flirt or get handsy. Couple this with teen movies that centered around house and frat parties and ways to lose your virginity and you get the distinct impression that sex was a big part of growing up in your early years for white kids. I've never gotten the slightest inkling that Asian women thought much of sex, god forbid even talking about it, and I'm not a young pup. Even the HE girls I've talked to said they don't even care about sex, don't miss it after divorce even. Most treat it like a job and don't seem to put much effort into the enjoyment of it(for the men) and just want to get it to the finish line. I know it is a job, but there are ways to make it more fun for both parties with some mental effort and imagination. While I'm pleasing my wife, and it's been hundreds of times over 25 years, I still think I make it fun. But with all the Asian girls I know, just making a joke about sex gets you the side eye.
Yes, I do believe that Latinas and also Blacks enjoy sex and live it much more than Asians. For the Asians(Japanese, Thai etc.) that are heavily involved in the sex trade, I believe it's more a means to an end than a lifestyle IMHO.
Being married all these years, I miss the GFE, which is why I thought the Rent a GF was a good idea.
