It's not because Europeans are (generally) less repressed & less prude than Americans (puritan heritage & all that), that they (again, generally) live their lives as you describe above. Although sometimes I wish we did. 😉
They (incl. Babi) agreed on a threesome, but Babi got second thoughts when things heated up, then was ok again (but not quite), then she got "third thoughts", and so on...
At least, this was definitely "real life", and not staged (though I wish it ended differently). But some will probably claim the opposite anyway.
