Many people are involved in kink, and many therapists are uncomfortable with it, or simply haven't tried to understand it. Often they will not talk about sex at all in a session, when it can be such a huge part of our life and the way we interact with our partners. This leaves some relationships within the kink umbrella vulnerable and without support from qualified therapists.
Many therapists simply misunderstand the dynamics involved. Some think it's purely a response to trauma. Some think even worse. But studies don't support the common misperceptions around kink. I follow Justin Lehmiller, one of the current sex researchers and educators, who is one in a long line of researchers and therapists like Kinsey, Shere Hite, Master's & Johnson, Dr Sue Johanssen, and Dr Ruth.
