Non-penetrative sex (also known as outercourse, dry sex, and dry humping) is sexual activity without vaginal, anal, or oral penetration, as opposed to intercourse, anal sex, or oral sex (which may or may not be penetrative).
The terms mutual masturbation and frottage are also used, but with slightly different emphases. NPS and outercourse are rather new terms, which is why such practices are sometimes still called "intercourse".
The term "outercourse" is something of a misnomer, as it contrasts "outer" with "inter" but the "inter" in "intercourse" means "between two people". It does not describe being inside or outside of the body.
It is less likely that bodily fluids will be exchanged, and so outercourse is often considered a practice of safer sex, as well as of birth control . Outercourse in preparation for intercourse can form part of foreplay.
