Consummate

In many traditions and statutes of civil or religious law, the consummation of a marriage, often called simply consummation, is the first (or first officially credited) act of sexual intercourse between two people, either following their marriage to each other or after a prolonged sexual attraction. The definition of consummation usually refers to penile-vaginal sexual penetration, but some religious doctrines hold that there is an additional requirement that there must not be any contraception used.

The religious, cultural, or legal significance of consummation may arise from theories of marriage as having the purpose of producing legally recognized descendants of the partners, or of providing sanction to their sexual acts together, or both, and its absence may amount to treating a marriage ceremony as falling short of completing the state of being married, or as creating a marriage which may later be repudiated. Thus in some legal systems a marriage may be annulled if it has not been consummated. Consummation is also very relevant in the case of a common law marriage.

In addition to these formal and literal usages, the term also exists in informal and less precise usage to refer to a sexual landmark in relationships of varying intensity and duration.

The relevance of consummation in a civil marriage varies by jurisdiction. For example, under section 12 of the Matrimonial Causes Act 1973, a refusal or inability to consummate a marriage is a ground of annulment in England and Wales, but this only applies to heterosexual marriage, because Paragraph 4 of schedule 4 of the Marriage (Same Sex Couples) Act 2013 specifically excludes non-consummation as a ground for the annulment of a same-sex marriage. Other common law jurisdictions, such as Australia, have abolished the legal concept of consummation.

In this case, usually, consummation, as well as cohabitation, are very important, they are needed - together with the presentation of the parties to society as spouses - in order to create the marriage itself.
