It specifies the frequency of sexual obligation based on the husband's occupation, although this obligation can be modified in the ketubah (marriage contract).
A man may not take a vow to abstain from sex for an extended period of time, and may not take a journey for an extended period of time, because that would deprive his wife of sexual relations.
Sex is permissible only within the context of a marriage.
In Judaism, sex is not merely a way of experiencing physical pleasure.
Indeed, even some Jewish movements have rejected some of these viewpoints in modern times.
Other points of view are more liberal than you would expect, and may offend those with more conservative sensibilities.

Trigger Warning: This page explains some traditional Jewish points of view about sex and sexuality that you may find offensive.A woman may not withhold sex from her husband as a form of punishment, and if she does, the husband may divorce her without paying the substantial divorce settlement provided for in the ketubah.Although some sources take a more narrow view, the general view of halakhah is that any sexual act that does not involve sh'chatat zerah (destruction of seed, that is, ejaculation outside the vagina) is permissible.Nevertheless, Judaism does not ignore the physical component of sexuality.
