Take away sight and you're forced to draw on your other senses. For a highly erotic experience, use the No Peeking Soft Twin Blindfold Set, part of the official Fifty Shades of Grey Pleasure Collection. There's one for each of you to wear. Slip them over your eyes and focus on touch, breath and the sounds your partner is making. These are great for discovering that there's so much more to sex than the visual elements.
