Non-penetrative sex or
outercourse is
sexual activity that usually does not include
sexual penetration. It generally excludes the penetrative aspects of
vaginal,
anal or
oral sexual activity, but includes various forms of sexual and non-sexual activity, such as frottage, mutual masturbation, kissing or cuddling. Some forms of non-penetrative sex, particularly when termed
outercourse, include penetrative aspects, such as penetration that may result from forms of
fingering or oral sex.
