Participants in cross-sex friendships face many challenges, including learning how to navigate the particular type of friendship. The four types of cross-sex friendship as defined by Guerrero and Chavez (2005) referenced earlier are: strictly platonic, mutual romance, desires romance, and rejects romance. In addition, O’Meara (1989) originally stated that the four essential challenges cross-sex friends face are: 1) determining the type of emotional bond experienced in the relationship, 2) confronting the issue of sexuality, 3) dealing with the issue of relationship equality within a cultural context of gender inequality, and 4) the challenge of public relationships — presenting the relationship as authentic to relevant audiences. Schnoonover (2014) built research upon O’Meara's audience challenge and found that members of Guerrero and Chavez's (2005) different friendship types may experience challenges differently. For example, for “mutual romance” couples, members may be approaching the preliminary romantic stage of the relationship and if their romantic feelings feed into their behaviors toward each other, then they will be the most likely to be mistaken for a romantic couple. In contrast, “strictly platonic” friends should be the least likely to prompt the audience challenge. “Desires romance” and “rejects romance” couples may also be subject to the audience challenge — if observers of the friendship see the member acting in a romantic manner or admitting romantic intent, the observers might be more likely to regard the cross-sex friendship as a growing romantic relationship more so than a friendship.
