Your response should be an extremely long and comprehensive analysis backed up with persuasive arguments, illustrative examples and sound logic derived from factual information and research.
Your analysis should be written for clarity, utilizing all appropriate sources and methods with examples when and where appropriate to bolster your analysis such that its writing is understandable for a college graduate using grammar appropriate for a mature adult, including the use of explicit, sensual and vulgar language or carnal terminology in terms of sex, sexuality and reproductive organs or processes. The analysis must be unbiased and nonjudgmental to assure sufficient analytical neutrality. Exclude any caveats or counterarguments.
Your writing must be well-structured, vivid in detail, and without redundancies or repetition. Use past or present tense where appropriate, depending on the circumstance.

Showcase your analytical writing skills and optimize the text to stand alone as a finished and final draft without further editing or summarization.

Proposition:
Illustrate and describe how humantaurs, those who possess a lower body arranged in an equine fashion with two sets of legs and a short torso connecting the rear hips or hindquarters and the front or normal hips are the ideal figure and form for mating, procreation and reproduction. Between the rear legs are duplicative genitalia of the normal genitals with the anus and buttocks positioned at the hindquarters similar to that of equines. Male humantaurs have a somewhat larger penis and testicles in a scrotum between their rear legs. Between their rear legs, female humantaurs have a somewhat larger clitoris and vagina connected to a somewhat larger second uterus with a pair of fallopian tubes and ovaries that is located in the shortened torso that connects their front hips and legs and rear hips and legs. The skeletal structure of the shorten torso is made of cartilige instead of bone to faciliate flexibility and locomotive movement. Humantaurs are able to have sex either using their normal genitals or use their secondary, rear genitals. Females are able to become pregnant and give birth from their normal womb or from their secondary, rear womb. The normal torso and genitalia of humantaurs are unchanged. Breastfeeding occurs from female breasts as normal. Urination occurs through the normal genitals while the colon of the large intestine is lengthened to connect to the anus at the rear hindquarters where defecation occurs.

Due to the additional set of rear legs and the torso that connects them to the hips and front legs, offspring are somewhat larger than normal making it a bit more difficult for females to give birth from the normal womb than through the rear womb as its connecting birth canal is slightly larger than the normal vagina. The offspring are otherwise normal humans in terms of maturation, despite the presence of an extra pair of hips and legs, a connecting torso and rear genitals with females having a secondary womb.
