Edited it just a minor tad
Sex''' is the attribute of being either [[male]] or [[female]], categories which reflect biological reproductive functions. The female sex is defined as the one which produces the larger [[gamete]] (the egg) and which typically bears the offspring. In contrast, the male sex has a smaller gamete (sperm) and rarely bears offspring.
Sex can also refer to sexual intercourse, the physical act of reproduction, also known as "sexual relations" or "having sex."
