“marriage and family therapists consumer update”
for information provided by the American Association for Family Therapy

Some of my areas of specialization and related AAMFT consumer information links are:
Marital Distress
Male Sexual Problems
Infidelity (Extramarital Affairs)
Premarital Relationship Checkups
Problematic Sexual Behavior (e.g., hypersexuality, sexual compulsivity, “sexual addiction”)
Cybersexual Dependency and Online Infidelity

The consumer information links may not capture the breadth of relational preferences or partner configurations. I do respect diversity and support an inclusive clinical stance that is culturally sensitive and LGBTQ-friendly.
