American singer-songwriter Madonna has been regarded as a sexual icon and defined by an author, as the leading sex symbol of the postmodern era. Many have considered Madonna's sexuality as one of the focal points of her career. The Oxford Dictionary of English (2010) credited her image as a sex symbol as a source of her international stardom. Her sexual displays have drawn numerous analysis by scholars, sexologists, feminists, and other authors. Due to her constant usage of explicit sexual content, Madonna faced censorship by MTV for her videos, as well as by other entities for her stage performances, and other projects.
