The American Association of Sex Educators, Counselors, and Therapists (AASECT) has very stringent requirements for training and experience in the area of sex therapy. Sexual health professionals have rigorous standards for academic preparation, supervised training and consultation, field-related experience and applied skills.
Training for Sex Therapy
Sex therapists read a great deal of academic books, attend many (many!) hours of clinical trainings and workshops in this specialty, do peer consultation, and study under seasoned clinicians who are considered masters in this field. Personally, I (Justin Pere) have studied with and experienced this field through Dr. Tina Schermer Sellers at Seattle Pacific University and Dr. Stella Resnick in Los Angeles, California.
