At the retreat, Jane and John were told to individually write a sentence using the words 'sex' and 'love.'

Jane wrote: 'When two mature people are passionately and deeply in love with one another to a high degree and that they respect each other very much, just like John and I, it is spiritually and morally acceptable for them to engage in the act of physical sex with one another.'

And John wrote: 'I love sex.'
