This so-called writer has confused ethics and is acting as judge rather than journalist.
Sex is an irresistibly interesting topic for most of us, and stories about other people's sexual adventures, and misadventures, are interesting.
People who are so judgemental about other people's sexual behaviour, would do well look inside themeslves for an explanation of why they are so keen to 'put the boot in'.
By offering a judgement about some else's life decisions damages the reputation of the victim.
'Opinions' (slander) such as this hardly comes from a state of moral mindfulness.
