In Hollywood shorthand, writers and filmmakers often use the phrase "less is more." The term can mean a variety of things, but generally it conveys the sense that sometimes you achieve more with less. A man walking out on his lover can simply say two words, and that may speak volumes more than a ten-minute diatribe.
Sometimes the most erotic images are those where you don't see everything. Your imagination has to fill in the blanks, and with that your subconscious runs wild. You start to imagine what the man looks like without his tiny little garment, then you're imagining his cock, then you're seeing it grow hard in your mind. Soon you're thinking of him wrapping his arms around you, rubbing his erection against your thigh, feeling the wetness from his precum on the bulb of his cock as he whispers in your ear, "I gotta fuck you right now."
