Sex may refer to:

Often a shortened way of referring to biological sex; that is, the sex assigned at birth – although often conflated with gender.

Or, the vast array of activities related to physically intimate behaviour. One should not restrict sex into only being penetrative (e.g. vaginal sex, anal sex). Sex is (perhaps viewed ideally) the activities that take place between two (or more) consenting individuals with the intention of evoking physical, emotional and/or romantic gratification; intimate pleasure; or, in some cases, merely an act of procreation used for reproduction.
