Also about one per year.
Biggest problem really is language and culture. In Australia, I'm mostly of little interest to the women there, and they're mostly of little interest to me. But at least we can speak English, so on the rare occasion that they have a brain in their head and are a cool person (instead of being the female version of an arrogant jerk), I can detect that. I don't remember ever detecting it, but I
could have.
If you can't communicate well, you can't really detect or appreciate any of these things.
In other countries you face other roadblocks. In Japan, if you want to "connect with" someone, I assume you have to be a robot yourself. In places like the Philippines or Thailand, it's pretty difficult to 'connect' with such simplisticness. So far I've found that Chinese are quite good, because they have more personality, are more free-thinking, and have more going on upstairs.
In cases where I've felt 'connection', it was because of something mentally complementary about us, and we could communicate fluently enough to establish it.
If you're trying to string together a 'connection' with what primitive language patterns you know of each others languages, good luck.
I suppose the ultimate solution is just for your home country to be sexually acceptable.
