According to a groundbreaking article in the Journal of the American Medical Association (JAMA) in 1999, sexual problems are common in women and men, but especially in women. In a survey of men and women aged 18-59 years, about 43% of women and 31% of men reported some sexual problem. The sexual problems reported by women in this study were in 3 primary areas: 1) lack of desire 2) difficulties becoming aroused or reaching orgasm  3) pain during intercourse. The most common sexual problems reported by men include: 1) premature ejaculation 2) erectile dysfunction and 3) low desire.

Sex Therapy:

Sex Therapy is a subspecialty of psychotherapy, focusing on the specific concerns related to human sexuality.  People of all ages, creeds, health status, ethnic backgrounds, whether partnered or single, may benefit from working with a psychotherapist who specializes in this area.  Certified Sex Therapists use specialized clinical skills and theoretical knowledge to help people solve their sexual concerns.

In most states and provinces, Sex Therapy is not a separately licensed or regulated profession, just as child psychotherapy or geriatric psychotherapy is not government regulated beyond granting the basic license to practice therapy.  To assure the public of highly qualified practitioners, the American Association of Sex Educators Counselors and Therapists (AASECT) provides voluntary certification to those therapists who have completed the rigorous certification process.  Only those therapists who have met these qualifications may designate themselves as “AASECT Certified Sex Therapists.” Mental Health Matters sex therapists are AASECT Certified.

What happens in Sex Therapy:

The Sex Therapy process is very similar to that experienced with other mental health practitioners.  The Certified Sex Therapist will meet with the person as an individual or with a couple in an office setting where an extensive history of the concerns will be taken.  The Certified Sex Therapist will note both the psychological and the physical components and will establish one or more diagnoses.  After this, a treatment plan will be proposed, usually with your involvement in its development.  In some instances, the Certified Sex Therapist may work closely with the person’s physician, nurse, or other therapist or counselor to establish causes and remedies for the problems. In no instances will a Certified Sex Therapist engage in any kind of sexual activity with a therapy patient/client, whether in the office or in any location.  To do so is a breach of ethics, and in some states and provinces is a crime. 
Many sexual performance problems can be resolved through either quality medical treatment and/or short term therapy. Don't let embarrassment or shame prevent you from seeking help and having the kind of sex life you desire. Contact Sexual Health Matters and get the help you need.
