Sex

From attraction to action, sexual behavior takes many forms. As pioneering sex researcher Alfred Kinsey put it, the only universal in human sexuality is variability itself.

Human interest in sex can be thought of as a built-in imperative: Survival of the species depends on it. And although sexual desire tends to wax and wane over the course of one's life, depending on external demands and relationship satisfaction, it often serves as a passport to bonding, intimacy, pleasure, and even human growth and healing.

People engage in sexual activity for many reasons: To feel alive, to maintain a vital aspect of human functioning, to feel desirable or attractive, to achieve closeness, or to please a partner they love. Sex can be one of the most difficult subjects for a couple to discuss: Bodies and interests change over time, and most people will experience some type of sexual problem at some point in life. Therefore, open communication is essential to intimacy and long-term satisfaction.
