Brazil IS latin; Latin american cultures are those that come from latin countries, like Spain, Portugal, Italy and France. Spanish, French, Italian and Portuguese, among many others, are languages that come from Latin, hence the term latin cultures.
Oh come on!! It's just the guys (the gay guys) that do that!! Anal is not comfortable or arousing, why would 50% or 90% of women of any country CHOSE to do it?
Obviously they like it. I hear of girls hating it and I hear of girls loving it. It's like other said, more culturally acceptable there. I read that survey as well awhile ago. Not from that link but I remember seeing it in the news.
Speak for your self. My wife loves anal. She's the ones that asks me to put it in her ass most of the time. She cums MUCH faster from anal than from vaginal, so most of the time she's able to cum more than once before I cum.
