Jessica Bawens-Sugimoto feels that in general, "slash and yaoi fans are dismissive of mainstream hetero-sexual romance", such as "the notorious pulp Harlequin romances". Deborah Shamoon said that "the borders between yaoi, shōjo manga and ladies' comics are quite permeable", suggesting that fans of BL probably enjoyed both homosexual and heterosexual tales. Kazuma Kodaka, in an interview with "Giant Robot" suggested that the Japanese yaoi fandom includes married women who had been her fans since they were in college. Dru Pagliassotti's survey indicates that loyalty to an author is a common factor in readers' purchase decisions. Yōka Nitta has noted a split in what her readers want - her younger readers prefer seeing explicit material, and her older readers prefer seeing romance. There is a perception that the English-speaking yaoi fandom is demanding increasingly explicit content, but that this poses problems for retailers. In 2004, ICv2 noted that fans seemed to prefer buying yaoi online. Andrea Wood suggests that due to restrictions placed on the sale of yaoi, many Western teenage fans seek more explicit titles via scanlations. Dru Pagliassotti notes that the majority of respondents to her survey say that they first encountered BL online, which she links to half of her respondents reporting that they get most of their BL from scanlations. In 2003, there were at least five BL scanlation groups. Japanese fan practices in the mid to late 2000s included the concept of the feeling of "moe", which was typically used by male otaku about young female characters prior to this. Robin Brenner and Snow Wildsmith noted in their survey of American fans that gay and bisexual male fans of yaoi preferred more realistic tales than female fans did. Shihomi Sakakibara (1998) argued that yaoi fans, including himself, were homosexually oriented female-to-male transsexuals. Akiko Mizoguchi believes there is a "shikou" (translated as taste or orientation), both towards BL/yaoi as a whole, and towards particular patterns within the genre, such as a "feisty bottom (yancha uke)" character type. Her study shows that fans believe that in order to be "serious" fans, they should know their own preferences, and "consider themselves a sort of sexual minority". She argues that the exchange of sexual fantasies between the predominantly female yaoi fandom can be interpreted that although the participants may be heterosexual in real life, they can also and compatibly be considered "virtual lesbians".
