ABSTRACT
For most couples in most cultures “sex equals intercourse.” People believe that intercourse is natural and instinctive. Yet 70% of intercourse among American couples is in the man-on-top position done in a routine, mechanical manner. Typically, the man initiates intercourse when he feels the woman is ready and guides intromission (putting his penis in her vagina). The traditional goal is simultaneous orgasm during intercourse, which can be intimidating rather than an empowering goal and which is seldom achieved.
