USA Today - Armie Hammer Allegations an Example of What Distinguishes BDSM from Sexual Violence

I was asked to give an expert opinion on this article by Jenna Ryu about the difference between BDSM and sexual abuse for USA Today.

"Explicit consent is the single most common characteristic in BDSM sexual interactions and is considered a fundamental tenet among those who practice BDSM," says Dulcinea Alex Pitagora, New York-based psychotherapist, sex therapist and BDSM specialist.In the same way that consent delineates traditional sex from rape, "it is also the factor that distinguishes non-pathological BDSM sexual interactions from pathological acts of violence."
