In Ancient Rome , fellatio was considered profoundly taboo.  Sexual acts were generally seen through the prism of submission and control. This is apparent in the two Latin words for the act: irrumare (to penetrate orally), and fellare (to be penetrated orally). Under this system, it was considered to be abhorrent for a male to perform fellatio, since that would mean that he was penetrated (controlled), whereas receiving fellatio from a woman or another man of lower social status (such as a slave or debtor) was not humiliating. The Romans regarded oral sex as being far more shameful than, for example, anal sex – known practitioners were supposed to have foul breath and were often unwelcome as guests at a dinner table.
