website refers to Jack's role within Doctor Who as "[continuing] what began with Ian Chesterton and continued later with Harry Sullivan". Whereas in the classic series the female "companions" were sometimes exploited and sexualised for the entertainment of predominantly male audiences, the producers could reverse this dynamic with Jack, citing an equal need amongst modern audiences to "look at good looking men". John Barrowman linked the larger number of women watching the show as a key factor in this. Jack is bisexual, and is the first televised Doctor Who character to be openly anything other than heterosexual. In Jack's first appearance, the Doctor suggests that Jack's orientation is more common in the 51st century, when humankind will deal with multiple alien species and becomes more sexually flexible. Within Doctor Who'''s narrative, Jack's sexual orientation is not specifically labelled as that could "make it an issue". On creating Jack, Davies comments "I thought: 'It's time you introduce bisexuals properly into mainstream television,'" with a focus on making Jack fun and swashbuckling as opposed to negative and angsty. Davies also expresses that he didn't make the character bisexual "from any principle", but rather because "it would be interesting from a narrative point of view." The bisexuality-related labels "pansexual" and "omnisexual" are also frequently applied to the character. Writer Steven Moffat suggests that questions of sexual orientation do not even enter into Jack's mind; Moffat also comments "It felt right that the James Bond of the future would bed anyone." Within Torchwood, the character refers to sexual orientation classifications as "quaint". In an interview with the Chicago Tribune, John Barrowman explained that "[He]'s bisexual, but in the realm of the show, we call him omnisexual, because on the show, [the characters] also have sex with aliens who take human form, and sex with male-male, women-women, all sorts of combinations." The term is also used once, in-universe, in the novel The House that Jack Built, when Ianto comments to a woman's remark about Jack, "He prefers the term 'omnisexual'." Costume While in his first several Doctor Who appearances, Jack did not have a set costume, Torchwood established a continual look for Jack which recalled that of his first Doctor Who appearance. The design has been described as "an iconic piece of sci-fi culture". A writer for Wired attributes much of Jack's appeal to the coat: "I think it has lots to do with that
