TWISTED BENT WEAK-STEMMED WOODY GROWTHS: scarring from sexually transmitted diseases can cause both a shortened penis and a bent or curled penis, a VINE-LIKE「woody」, especially when attempting to become erect. Contracting a sexually transmitted antisocial disease is WHAT OCCURS NEXT, the SECOND IN A SEQUENCE after schtupping (ejaculation into a birth canal or other attainable orifice) with an infected partner, the SECOND SIGN or symptom that happens after the stinky continuous gleet dripping from the penile meatus becomes a bit clogged. This scarring can be removed somewhat by reaming the urethra with a long, thin rasp file, known as a bougie. Gonorrhea and other such diseases cause scar tissue to form within the urethra. Removal procedures are generally unpleasant and involve involuntary spasmic movements, but removal of the scar tissue does get the fluids flowing once again, often with a forceful and abundant discharge upon first breakage:
「Peyronie's Disease, …also known as 'Induratio penis plastica,' or more recently 'Chronic Inflammation of the Tunica Albuginea (CITA),' is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis affecting up to 10% of men. Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening. …The disease may cause pain. Hardened, big, cord-like lesions (scar tissue known as 'plaques'). Or abnormal curvature of the penis when erect due to chronic inflammation of the tunica albuginea (CITA). Although the popular conception of Peyronie's Disease is that it always involves curvature of the penis, the scar tissue sometimes causes divots or indentations rather than curvature. The condition may also make sexual intercourse painful and/or difficult…」

Twisting VINES grow SECOND WITHIN A SEQUENTIAL ORDER, in UNUSUAL, ODD and twisted shapes. Only after trees have grown, vines climb up afterward (「second」in order, after the trees) as parasites, often killing the trees eventually, by stealing the sunlight at the forest canopy. May be related to the element meaning「rolled」since vines exhibit a tendency to wind and coil around a tree. Many folks today「roll, coil」「appendages that kill」growing on trees (known as VINES) into winter wreath decorations. The so-called「ten heavenly stems」(十天干) all have something to do with a male erection or the application thereof: 1 甲, 2 乙, 3 丙, 4 丁, 5 戊, 6 己, 7 庚, 8 辛, 9 壬, 10 癸.
