Les Psaumes 1:3 Halakha : Mishneh Torah, Human Dispositions & Mishneh Torah, Sabbath

Though one's wife is ever lawful to him, it is proper that a disciple of the wise should demean himself with sanctity, and not be like a rooster;⁶Berakot, 22a. G. a Sabbath to Sabbath visitation,⁷Ketubot, 62. C. if there be no physical reason to the contrary, not in the beginning of the night⁸Nedarim, 20; Niddah, 16. C. G. when in a state of satiety, nor at the end of the night when hungry, but about midnight after the food in his bowels be digested, unaccompanied by either exceeding boisterousness or profanity of mouth with vain words, even between themselves. Behold, it is traditionally said that the Verse, "And he declareth unto man what his language is" (Amos. 4.13), the sages interpreted: "Even on account of indecent conversation a man carries on with his own wife, he will have to render an accounting" (Hegigah. 5b). Both of them shall not be intoxicated, nor sluggish, nor in mourning; nor either of them in such state; nor when she be asleep, nor by overpowering her contrary mood; but with the consent and happy mood of both, with few pleasant and light-hearted words to please her being, stilling his urge diffidently and not impudently and dissociate immediately.

Marital relations is from the delights of Shabbat. Therefore Torah scholars [fulfill] their [set] time from one Shabbat night to [another] Shabbat night. It is permissible to have intercourse with a virgin [even] at the outset, and there is no [transgression] of (the Shabbat laws) on account of injuring or on account of the pain [caused] to her.
