Does culture matter?

If you've been following the blog you'll notice my musings about why some people like anal, why many men love it, and why others are more open to the idea.

Now, we know that in the past in some societies the practise of anal sex was widespread. Could that also be true today?

So far most of the contributors to the blog have been (or appear to be) native English speakers which puts them in a very similar culture. In western culture anal sex is gradually becoming more of an accepted thing, but I know I have readers from around the world and would love to here about their experiences.

Is it acceptable or frowned upon where you live?
