Fred and Laura go on walks, take weekend breaks away, amble round markets and often have meals out.

Amid the debate, however, one question is rarely asked - what motivates men to pay women to sleep with them? Fred lives in a remote rural area and for many years he was a full-time carer, looking after his mother.
