Favorable time for sexual intercourse

You should not copulate on a full stomach, because this interferes with digestion and leads to diseases caused by moving on a full stomach, acting faster and more severely. And if this already happens to someone, then after copulation you should move a little so that the food settles in the stomach and does not float up, and then sleep as long as possible. It is not proper, however, to copulate on an empty stomach, for this is even more harmful and difficult for nature, more deadly for the innate warmth and brings on thinness and dryness; on the contrary, it should copulate during the descent of food from the stomach, after the complete completion of the first and second digestions, in the middle of the third digestion. This happens in different ways for different people, and one should not pay attention to the words of those who say: “copulation should occur after the complete, comprehensive completion of digestion,” for this is the time when the stomach is empty and the body begins to assimilate food, and in each the organ contains a remainder of the nutrient undergoing the fourth digestion. Some people have a favorable state for copulation at the beginning of the night, and this is the most favorable time for copulation for them, both for the reasons mentioned above and in another respect, namely, because it is followed by a long sleep, and strength returns again. And in women, during sleep, the seed is established in the uterus.

One should copulate only with healthy lust, which is not caused by looks, thoughts, itching or burning, but only by the abundance of semen and the fullness of the genital organ; all this contributes to a healthy state of male power. One should abstain from intercourse in case of indigestion and after strong bowel movements through vomiting and laxity, during haida and sudden bloody diarrhea, as well as after bodily and mental movements, during the passage of urine and feces and after bloodletting. As for old diarrhea, intercourse sometimes dries it out with its drying effect and diverts matter from the intestines in the other direction. It is appropriate to avoid intercourse in hot weather and in hot areas. A man should abstain from them when his body is overheated or cold, but it is still healthier after overheating than after cooling down. It is also better to copulate after being moist than when dry. The best time for balanced people is the time when, as established by experience, a person, having copulated after a certain period of abstinence from copulation, feels satisfied, and all his senses are heightened.

Seed that gives birth and that does not give birth. The seed of a drunken man, an old man, a child, and a man who copulates too often does not give birth; the seed of one whose organs are damaged rarely gives birth to a healthy child. If the penis is very long, the distance that the seed travels is extended, so that it reaches the uterus when its innate warmth has already weakened, and in most cases such seed does not give birth. A sign that a person has recently copulated: in his urine there are threads and fibers intertwined with each other.
