A truly romantic, and meaningful masturbation session. Legs spread, ass naked, scented candles burning, rose petals on satin sheets etc. Must last at least an hour to be considered a Sensual Wank.
"Hey guys, don't come in my room for another three hours. I'll be engaged in a Sensual Wank."
"Man, you Sensually Wank everyday. I was going to borrow a shirt yesterday, but the door was locked and Marvin Gaye was playing all afternoon."
