The American Association of Sexuality Educators, Counselors and Therapists (AASECT) is a professional organization for sexuality educators, sexuality counselors and sex therapists. Given that more than half of the population of adults face sexual dysfunction at some stage of their life, Certified Sexual Therapists or CSTs approach the matter directly, using a bio/psycho/social approach that includes behavior-based solutions. Prospective educators, counselors and therapists are trained in interventions methods specially designed to target sexual issues.
