Becoming a sex therapist requires a significant investment in education and training. Typically, you'll need a master's or doctoral degree in a related field such as psychology, social work, or counseling. Following your degree, specialized training in sex therapy is essential, often through post-graduate programs or certifications. Licensing requirements vary by state or region, but usually involve supervised clinical experience and passing an exam. Successful sex therapists possess strong communication skills, empathy, and a deep understanding of human sexuality.
