Joesph smith's sexuality? If this is what you are referring to the only court records I know of were made bey affidavits made by women who claimed to have had sexual relations with Joseph Smith and made these claims long after (I think decades) after his death. That is not evidence. I can file an affidavit against anyone else claiming to have had sexual relations.
When did Emma Smith ever say Joseph Smith had extra marital seuxla affairs?
