「Wood of rancid human swine」describes the location of the source of the problem, the urethra within the CORE of the penile shaft encased within the corpus cavernosum, and/or the SMEGMA surrounding the CORE, KERNEL, NUCLEUS of human sexuality, the glans penis of the male and the glans clitoris of the female.
　「Tree with wild boar or sow」or「wild boar or sow hardwood」depicting the zeal and fervor with which a wild sow will root for truffles around certain trees, or for a horny boar. An IRRESISTIBLE SEXUAL PHEROMONE present in both male and female humans at the CORE, KERNEL, NUCLEUS of human sexuality, and it is unquestionable that sexuality is at the NUCLEUS, KERNEL, CORE OF HUMANITY, literally indicating the sex gametes of spermatozoon and ovum:「The black truffle's penetrating aroma is also said to ooze promises of sexual delight. Epicureans liken the scent to that of the tousled sheets of a brothel bed. Biochemists, drawing on a less exotic frame of reference, have identified the pheromone in truffles as the same type that makes male pigs alluring to sows. …Misguided female boars would dig them up in fits of lust and scatter their spores throughout the forest. The irresistible pheromone, known as androstenol, is produced in the testicles and secreted in the saliva of the boar. This chemical sexual attractant transports the inamorata into a fever of unbridled passion. Interestingly, androstenol is also present in women's urine and secreted by men's armpit glands.」

　RADIOACTIVE WASTE can be likened to human sexuality as something else that never goes away, or at least has a half-life of hundreds of thousands of years:「woody of rancid human.」…or to SMEGMA, naturally, the stuff found at the core within the male and female prepuce.
　See both 實 and 実 for details that plainly explain where the CORE, KERNEL, NUCLEUS is located and may be quite easily discovered by anyone seeking to find it.
　「…[T]he vagina has few nerve endings, and therefore cannot create an orgasm on its own. Instead of thinking of the vagina and clitoris as separate entities, try thinking about them as a network of nerves and muscles.」
　「In reality, total separation between the vagina and clitoris is mostly artificial, and often based on a misunderstanding of what, where, and how big the clitoris really is. The clitoral organ system actually surrounds the vagina, urethra and anus. Rather than thinking of an orgasm as 'vaginal' or 'clitoral,' it makes more sense to think of orgasm in terms of the feelings that came along with it. In the end, an orgasm is an orgasm is an orgasm!」
　「Here's a little bit of history for you: Sigmund Freud made a pronouncement that the 'mature' woman has orgasms only when her vagina, but not her clitoris, is stimulated — this is commonly referred to as the “vaginal orgasm”. The emphasis on stimulation from penetration made the man's penis central to a woman's sexual satisfaction. It is important to emphasize that Freud did not base his theory upon a study of woman's anatomy, but rather upon his assumptions of woman as inferior to men.」
　「Back to the basics, stimulating the clitoris and (for some women) pressure in or around the vagina can cause pelvic fullness and body tension to build up to a peak. During sexual excitement, the clitoris swells and changes position. The blood vessels through the whole pelvic area also swell, causing engorgement and a feeling of fullness and sexual sensitivity. The inner vaginal lips swell and change shape, and the vagina balloons upward, causing the uterus to shift position. Orgasm is the point at which all the tension is suddenly released in a series of involuntary and pleasurable muscular contractions in the vagina, uterus, and/or rectum.」
