Halakhah - Marriage, sexuality and niddah

Sex as a mitzvah

Sex is not simply treated as a regrettable concession to human weakness. Within marriage, it can fulfil mitzvoth, commandments, and express intimacy and joy. Genesis 1:28 supplies the procreative command; Exodus 21:10 provides a basis for onah, marital sexual obligation, developed by rabbinic law. These references are paraphrased from THE JPS TANAKH: Gender-Sensitive Edition (2023).

Procreation and conjugal pleasure are distinct purposes. A relationship can have value beyond whether every sexual act produces a child. Onah also challenges the idea that only one partner's desire matters: the other's needs and marital responsibilities count. It should not be turned into a justification for coercion. A duty of relationship must be interpreted with care for the person involved.

Traditional halakhah places these purposes within marriage and sets boundaries on permitted relationships. A defender argues that stable commitment protects intimacy and family life from purely private appetite. A critic asks whether marriage alone guarantees mutual respect, or whether equally committed relationships outside its traditional definition can embody the same goods. The disagreement requires reasons about the purposes and authority of the boundary, rather than calling sex either inherently holy or inherently shameful.

Niddah and mikveh

Niddah names a halakhic status associated with menstruation and the rules governing it. Leviticus 15:19 describes menstrual ritual status; Leviticus 18:19 prohibits sexual intercourse during that status. Ritual impurity is not the same category as moral guilt, dirtiness or lesser human worth. Menstruation is not presented as a deliberate wrongdoing.

Later halakhic practice develops separation, checking, a count of clean days and immersion in a mikveh, a ritual bath with legally specified water and construction. In widely practised Orthodox observance, seven clean days precede immersion, after the earlier stage of the process. Details and minimum intervals vary with custom and circumstances; the biblical seven-day reference is not a complete description of every later timetable. Ordinary washing does not replace ritual immersion.

Couples practising these rules refrain from sexual relations during the relevant period and observe further boundaries according to their tradition. Immersion permits resumption of married sexual life. Some experience the rhythm as meaningful anticipation, discipline or renewal. Others find its restrictions intrusive or its gendered burdens difficult. Those reported effects are possible experiences, not universal facts about every woman or couple.

The judgement “niddah is wrong because impurity means women are sinful” rests on a mistaken category. Correcting it does not settle the ethical debate: one can still question unequal burdens, bodily autonomy and language that is experienced as demeaning. A defender must address the actual objections, not merely repeat the distinction.
