Of these individuals, 56% reported having sex with more than one cross-sex friend (Afifi & Faulkner, 2000). What unique challenges do cross-sex friendships face? (continued)

8. 8 ◦ Among those who are sexually attracted to a cross- sex friend, the primary reasons for not pursuing a sexual relationship are: avoiding a “break up,” avoiding being hurt, and avoiding social disapproval (Messman et al., 2000).

9. 9 Relatively little research has examined friendship among individuals who identify as bisexual, lesbian, or gay. What research findings have emerged regarding friendship among individuals who identify as bisexual, lesbian, or gay? This research has demonstrated similarities with and differences from the findings reported for individuals who identify as heterosexual.

10. 10 Similarities include:  Friendship network size.  Desired characteristics: Seek friends with similar characteristics. Lesbians and gay males have more friends who are lesbian or gay than heterosexual or bisexual; bisexual individuals have more friends who are heterosexual than bisexual, lesbian, or gay (Galupo, 2007).

11. 11 Sexual Orientation of Friends Among Lesbians, Gay Males, and Bisexual Individuals (Galupo, 2007)

12. 12 Differences include:  Sex differences in self-disclosure and shared activity are not observed in friendships among gay males and lesbians (Nardi & Sherrod, 1994).  Sex differences in relationship conflict are not observed in friendships among gay males and lesbians (Nardi & Sherrod, 1994).

13. 13  The emotional bond challenge and sexual challenge manifest in same-sex friendship as opposed to cross- sex friendship for individuals who identify as gay or lesbian. 76% of gay males report having had sex with one or more close friends; 59% of lesbians report having had sex with one or more close friends (Nardi, 1992).

14. 14 Data regarding the frequency of sex with friends among individuals who identify as bisexual are not available.  The emotional bond challenge and sexual challenge manifest in both same-sex friendship and cross-sex friendship for individuals who identify as bisexual.
