By the 1970s, writing for "Woman's Own" Rayner had established herself as one of four new and direct "agony aunts", alongside Marjorie Proops, Peggy Makins (aka Evelyn Home) at "Woman" and J. Firbank of "Forum". Her advice in the teenaged girls' magazine "Petticoat" caused controversy. In 1972 she was accused of "encouraging masturbation and promiscuity in prepubescent girls". Her direct and frank approach led the BBC to ask her to be the first person on British pre-watershed television to demonstrate how to put on a condom, and she was one of the first people used by advertisers to promote sanitary towels.
