Mutunus Tutunus
In ancient Roman religion, Mutunus Tutunus or Mutinus Titinus was a phallic marriage deity, in some respects equated with Priapus. His shrine was located on the Velian Hill, supposedly since the founding of Rome, until the 1st century BC. During preliminary marriage rites, Roman brides are supposed to have straddled the phallus of Mutunus to prepare themselves for intercourse, according to Church Fathers who interpreted this act as an obscene loss of virginity.
