Flirt with him. Be playful, tease him, talk sexy once in a while, gaze into his eyes with a “come here, big boy†twinkle, offer sexy kisses and physical touches. Why do we think we can quit doing the things we did when we were first falling in love and expect our relationship to stay strong? The relationships that endure are those where the couple stays “in loveâ€. That means flirting, being playful, being sexy and sensual, and remembering why we fell in love in the first place. Benefit to you: You’ll both feel younger, friskier, and more in love. Why it works: Flirting is a kind of play and playfulness helps cement your bond. And adding the sexual energy to the mix keeps the sexual side of your relationship alive and vibrant. Remember this, when the sexual side of your relationship dies, you become roommates at best.
