The porn video tag "asmr-female-voice" refers to a video featuring an adult female performer who creates ASMR (Autonomous Sensory Meridian Response) sensations through her voice. ASMR is a tingling sensation that starts at the scalp and moves down the body, often resulting in relaxation or euphoria. The "female-voice" part of the tag emphasizes that it's a woman's voice specifically creating these sensations for the viewer.
