Turn off every light in the house, crack open a pack of glow sticks and markers, and use them to draw patterns directly on each other’s naked skin in complete darkness.

You can’t see anything except the neon trails you’re creating—swirls across their stomach, lines down their arms, circles around their chest, abstract designs on their thighs. The glow sticks are cool against warm skin, and you’re both focused entirely on the sensation of being drawn on, of creating temporary art on a living canvas. You can write words, trace shapes, follow the contours of their body with light. When you’re done decorating each other, step back and look at what you’ve created—two glowing, marked bodies in the dark, covered in your mutual handiwork. Then get closer and watch the patterns shift and blur as you move together, the neon streaks smearing and mixing as you touch. The glow sticks will fade eventually, but for now you’re both walking art installations, lit up and ridiculous and surprisingly beautiful in the darkness. Nothing says romance like turning your partner into a rave.
