After Mormons learn that Joseph Smith married between 30 and 40 wives and at least 10 women who were already married to other living men. They quickly proclaim that he didn't have sex with his wives. He married them in spirit only.
Let me dispel the bullshit. Joseph Smith had sex with his plural wives and below is the proof.
Joseph Smith's original 1831 polygamy revelation, given to a group of married men while they were visiting a Native-American tribe, also explains procreation as the purpose of polygamy:
Joseph Smith had a plan to make the Lamanites "white and delightsome":
"For it is my will, that in time, ye should take unto you wives of the Lamanites and Nephites, that their posterity may become white, delightsome and Just, for even now their females are more virtuous than the gentiles." - Prophet Joseph Smith, The Joseph Smith Revelations Text and Commentary, p. 374-376,
Brigham Young taught that "This is the reason why the doctrine of plurality of wives was revealed, that the noble spirits which are waiting for tabernacles might be brought forth." (Discourses of Brigham Young, p. 197.)
"Because of claims by Reorganized Latter-day Saints that Joseph was not really married polygamously in the full (i.e., sexual) sense of the term, Utah Mormons (including Joseph's wives) affirmed repeatedly that Joseph had physical sexual relations with his plural wives-despite the Victorian conventions in nineteenth-century American religion which otherwise would have prevented mention of sexual relations in marriage."
Faithful Mormon Melissa Lott (Smith Willes) testified that she had been Joseph's wife "in very deed." (Affidavit of Melissa Willes, 3 Aug. 1893, Temple Lot case, 98, 105; Foster, Religion and Sexuality, 156.)
In a court affidavit, faithful Mormon Joseph Noble wrote that Joseph told him he had spent the night with Louisa Beaman. (Temple Lot Case, 427)
Emily D. Partridge (Smith Young) said she "roomed" with Joseph the night following her marriage to him and said that she had "carnal intercourse" with him. (Temple Lot case (complete transcript), 364, 367, 384; see Foster, Religion and Sexuality, 15.)
In total, 13 faithful latter-day saint women who were married to Joseph Smith swore court affidavits that they had sexual relations with him.
Joseph Smith's personal secretary records that on May 22nd, 1843, Smith's first wife Emma found Joseph and Eliza Partridge secluded in an upstairs bedroom at the Smith home. Emma was devastated.

Smith's secretary William Clayton also recorded a visit to young Almera Johnson on May 16, 1843: "Prest. Joseph and I went to B[enjamin] F. Johnsons to sleep." Johnson himself later noted that on this visit Smith stayed with Almera "as man and wife" and "occupied the same room and bed with my sister, that the previous month he had occupied with the daughter of the late Bishop Partridge as his wife." Almera Johnson also confirmed her secret marriage to Joseph Smith: "I lived with the prophet Joseph as his wife and he visited me at the home of my brother Benjamin F." (Zimmerman, I Knew the Prophets, 44. See also "The Origin of Plural Marriage, Joseph F. Smith, Jr., Deseret News Press, page 70-71.)
Faithful Mormon and Stake President Angus Cannon told Joseph Smith's son: "Brother Heber C. Kimball, I am informed, asked [Eliza R. Snow] the question if she was not a virgin although married to Joseph Smith and afterwards to Brigham Young, when she replied in a private gathering, "I thought you knew Joseph Smith better than that.""
