The Compendium of Bheḷa 1.7

For all the sense faculties decay as one ages; / therefore, at every age one should approach a woman at the proper time.

However, one should not approach women when one's strength has not been replenished; / one should not practice in non-vaginal parts, and should avoid animal wombs.

One should not hold back an urge when it has arrived; having engaged [in intercourse], one should touch cold water; / but one should not engage when tired, nor newly eaten, nor distressed, nor agitated,

nor emaciated, nor having eaten excessively, or depressed should one engage in intercourse. / One who is constantly measured in speech, eating unctuous food, young, […] should practice.

Possessing abundant and unctuous semen, sleeping and eating according to the season; / one should avoid an aged woman, one near delivery, a diseased, dirty, emaciated,

deformed woman, one desiring another, and one with a putrid alimentary tract. / The strength, health, lifespan, body, and luster of embodied beings

is lost, indeed, having approached such a woman, as if reaching premature old age. / A man should practice intercourse season by season at the proper time:

in the rains after nine nights, and in autumn after ten nights; / in the winter season after five days, and likewise in the cold season after seven days;

in spring after a fortnight, but in summer one should practice month by month; / in the last month of the hot season, one should entirely avoid intercourse.

Or, endowed with youth, enthusiasm, strength, and unctuousness, / bathed in cool water, with agreeable garlands and ointment,

not devoted to excessive exercise, eating milk, meat, and ghee; / [with women] wearing agreeable garlands and garments, adorned with agreeable ornaments,

endowed with pleasing youth, beloved, compliant with pleasing speech, / exhilarated, at all times one should approach women with half one's strength.

One should avoid the fourteenth, the fifteenth, and the eighth [lunar days]; / one should drink milk and ghee daily, which promotes lifespan and is wholesome.

For this confers strength and complexion, and likewise promotes health; / a man should have body hair and nails cut three times a month.

One should constantly wear herbs and auspicious gems, / and should also repeat the eternal mantras spoken by Brahmā:

"May that wind and those vital breaths that are constant never depart from my body; / may Indra give me strength, and may the waters bestow auspiciousness on us."

Having eaten or having approached women, / reciting this mantra of the sages and touching water, his lifespan is not diminished. / Thus said the venerable Ātreya. / Thus the seventh chapter in Bheḷa. / Eighth chapter. / Now we shall explain the chapter on eating according to measure; thus said the venerable Ātreya:
