Few therapists are trained to provide affirmative, effective therapy for clients who are sexually nontraditional and from various multicultural backgrounds. The author explores several models that can be used to increase students' understanding of such clients. Pederson's Triad model uses the theory of three conversations at work in the counseling process: (1) the overt verbal and nonverbal expressions between therapist and client; (2) the client's covert internal conversation about the counselor and the counseling process; and (3) the therapist's covert internal conversation about the client and the counseling process. Two additional people, who serve in the roles of pro-counselor and anti-counselor and are of a similar background to the client, give voice to unexpressed feelings of the client. The Klein Sexual Orientation Grid (KSOG), a self-report instrument, allows the identification of seven variables: sexual attraction, sexual behavior, sexual fantasies, emotional preference, social preference, self-identification, and heterosexual/gay lifestyle. It demonstrates the fluidity of sexual orientation. A third tool is the sharing of coming out stories of bisexual women and men. Finally, mixed orientation marriages and racially mixed marriages are addressed and 13 specific training techniques for therapists countering biphobia are discussed. Contains 27 references. (KM)
