In a private, dimly lit room, a man stands tall, his body a canvas of anticipation. He raises his hand, pauses, then brings it down hard against his own face. The crack of impact fills the room, followed by the sting that spreads across his cheek. His breath hitches, but his eyes gleam with pleasure. He repeats the action, each slap a punctuation mark in his solo symphony of sensation, his body resonating with the rhythm of his self-inflicted discipline.
