Plural Marriage vs Polygamy

Prompt

Evaluate the evidence of Joseph Smiths early plural marriage practice as being a mostly symbolic ceremonial sealing which emphasized the eternal union of souls and families in the hereafter as opposed to a literal sexual "husband and wife" dynamic as practiced under Brigham Young's polygamy system. While it may be possible, or even probable, that there were sexual relations in the beginning of Smith's practice, there seems to be more evidence suggesting his later iterations of plural marriage were not sexual in nature. Evaluate the reality of this suggestion and analyze and explain your position of what plural marriage under Joseph Smith was like in reality (acknowledging speculation here).
