If one escapes and does not reach an egg, my understanding is that it is not considered fornication. That is an acceptable loss; how often if ever this happens, I don't know. However realize that even one drop of semen contains thousands of sperm, so even one drop escaping the body is fornication, but a single sperm that escapes without seminal loss is not. Sexual energy is going to be used up in the sexual act. Hormones and chemicals are going to be released. It actually take a good deal of energy to sustain an erection and for a woman to become ready. But these are acceptable usages as well. It is nothing compared to energy loss of the orgasm/ejaculation. Right. Esoterically, fornication is the orgasm/ejaculation in any form. Fornication is the method of sexuality of the animal kingdom; it is incredibly wasteful from an individual standpoint but it provides the Earth with energy its needs; the animal kingdoms are related with group-will. But once we reach the intellectual-animal kingdom (incorrectly called the human kingdom) things work differently because it is here that we begin to develop individuality. The current "humanity" is really just a physical human appearance with an intellectual animal mind, an animal will, and an animal sexual behavior. The true human is born when he dies to his animal sexuality by working with sexual transmutation, in order to become a "Twice-Born" to be "Born Again" of the Spirit. The true human is Christ Mind, Christ Emotion, and Christ Will. This is why Christ says that anyone who wants to follow me his must deny himself; that is to say, deny your animal self, to destroy it. I died from the mineral kingdom and became a plant; I died to vegetable nature and became an animal; I died to animality and became a human being. Next time I will die to human nature and lift up my head among the angels. Once again I will leave angelic nature and become that which you cannot imagine. —Rumi Here Rumi is talking about the death of the human to become an angel. But what he is calling the human is really better worded as the intellectual animal, and the angel is the true human being. So, when the animal gets intellect, God says, "Thou shalt not eat of the fruit of good and evil" because he wants us to eventually become a real human being. "Thou shalt not fornicate," which is the real wording of the Sixth Commandment, is related with the Sixth sephera, which is the seat of the human soul (Tiphereth, Superior Manas). So to reach the sixth sephera you have to listen to the sixth commandment.
