Many of us equate "sex" with "intercourse" and use those words interchangeably. Yet highly satisfying sex doesn't have to be limited to penetration -- and doesn't even have to include it at all, reported Cable News Network (CNN) quoting a study report.

"Our purpose was to understand more about women's experiences with ... the kinds of touch they find pleasurable and how clitoral and vaginal stimulation contribute to their orgasms," she explained.
