The presentation of human sexuality information within counselor education programs seems inconsistent, leaving counselors typically underprepared to handle the sexuality-related components of many clients' distress. Addressing this gap, the present article, using guidance from the American Association of Sexuality Educators, Counselors, and Therapists (AASECT), proposes 10 human sexuality counseling competency domains to aid counselors in working more effectively and comprehensively with clients. These domains are: Ethical/Professional Behavior, History and Systems, Anatomy/Physiology, Sexual Identity, Sexual Development, Intimacy and Interpersonal Relationships, Pleasure and Sexual Lifestyles, Sexual Functioning, Health/Medical Factors, and Sexual Exploitation. Clinical implications are discussed and include improved case conceptualization and developing counselor competence. Opportunities for future research are presented as they relate to counselor education and training.
