Q. Titius Moneyer of the Roman Republic from 90 BC to 90 BC.
Q. Titius was one of the moneyers for the year 90 BC - he is not otherwise known.

Gens Titia was a plebeian family in Rome. They are rarely mentioned in the Republican period, and did not rise from obscurity until a very late time. None of the members held the consulship until Marcus Titius in 31 BC.

Titius seems to be a patronymic surname based on the praenomen Titus, which was presumably an ancestral name. It was a very common name amongst Romans, but it has been conjectured that it was introduced to Latin through Titus Tatius, a Sabine king in the time of Romulus, who came to Rome with many of his subjects. The Titii may therefore originally have been Sabines.

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. Arnobius says that Roman matrons were taken for a ride (inequitare) on Tutunus's "awful phallus" with its "immense shameful parts", but other sources specify that it is brides who learned through the ritual not to be embarrassed by sex: "Tutinus, upon whose shameful lap sit brides, so that the god seems to sample their shame before the fact. The god's name is related to two infrequently recorded slang words for penis in Latin, mūtō (or muttō) and mūtōnium. "Mutto" was also used as a cognomen. Tītīnus perhaps from tītus is another slang word for "penis". (wikipedia)
