The thing I've noticed with Vietnamese women, Rosie included, is that they have fun. You're either going to get mechanical sex or a girl who knows how to enjoy what she does. The women also tend to be down to earth and easy to get along with. I've had mid sex with some Vietnamese women but for the most part they were friendly and cordial. There's probably one or two I can think of that didn't fit the bill.
I don’t break it down by ethnicity or nationality, because I’ve probably had both fantastic rapport and shitty rapport with every “type” of girl; so, I think it’s more about the individual. However, it’s incomparably more enjoyable for me when I actually like the girl and there’s more of a connection than an hour fucking a total stranger I can’t talk to. OTOH, I’ve had a couple of great experiences (like Vila @ DDY/SL) where the girl didn’t speak a word of English but fucked me like we were in love...that’s also hot AF.
It’s funny, because IRL, nothing is hotter to me than completely anonymous sex with a girl I just met and have barely talked to; but with providers, the better the connection, the more I enjoy the sex. Before I was married, I once met a girl online and flew to Phoenix to meet her. We agreed that if the attraction was mutual in person, we’d just kiss when I walked out of the gate and hold hands walking to her car, but that we wouldn’t say a single word to one another until my cock was already inside her. We walked to her car in silence but stopping every once in a while to kiss and it wasn’t until she straddled me and I was inside her to the hilt that we finally said “Hi.” Closest I’ve ever come to fucking a complete stranger without knowing her at all. The shirt I was wearing has been demoted to being one of the old shirts that I wear under my hockey shit, but I think of that every time I put it on.
