> I’ve heard the opposite, that South Americans often complain about smelly European tourists who don’t shower frequently enough.

That's completely different. Odors from different ethnies can be easily disturbing. We don't smell the same and we are not used to it.

> I’m also not sure I’d choose to use Africa as an example of healthy sexuality, what with the aids epidemic and FGM.

Actually they have aids epidemic BECAUSE sex is so natural there. There is nothing natural with stopping a sensual escalation and putting a rubber on your penis. Education helped us to do this, and saved us from dying in mass and having unwanted pregnancy, but it has a serious price on the way we handle sex.
