הָאִשָׁה שֶׁהִרְשַׁת אֶת בַּעִלָהּ אַחַר הַנִּשּׂוּאִין שֶׁיִּמְנַע עוֹנָתָהּ הֲרֵי זֶה מֻתָּר. בַּמֶּה דְּבָרִים אֲמוּרִים בְּשֶׁהָיוּ לוֹ בָּנִים שֶׁכְּבָר קִיֵּם מִצְוַת פְּרִיָּה וּרְבִיָּה אֲבָל לֹא קִיֵּם חַיָּב לִבְעל בְּכָל עוֹנָה עַד שֶׁיִּהְיוּ לוֹ בָּנִים. מִפְּנֵי שֶׁהִיא מִצְוַת עֲשֵׂה שֶׁל תּוֹרָה שֶׁנֶּאֱמַר (בראשית א כב) "פְּרוּ וּרְבוּ":
It is permissible for a woman to authorize her husband to ignore her conjugal rights. When does this apply? When he has children already and has fulfilled the mitzvah to be fruitful and multiply. If, however, he has not fulfilled the mitzvah of being fruitful and multiplying, he is obligated to engage in sexual relations whenever his conjugal duties require, until he fathers children. For this is a positive commandment of the Torah, as [Genesis 1:28] states: "Be fruitful and multiply."
