By that standard only eunuchs should be priests. All physically normal males have a very powerful sexual impulse. All homo priests are constantly tempted to go for the boys, and all abstinent hetero priests are constantly tempted to go for the young women; there is no third option. The LEAST lustful priest would be the one who has a lawful outlet for his sex drive, namely, marriage.
Besides, look at history: ordaining married priests worked just fine for 1000 years.
Exactly, Our Lord's standard.
"For there are eunuchs, who were born so from their mother's womb: and there are eunuchs, who were made so by men: and there are eunuchs, who have made themselves eunuchs for the kingdom of heaven. He that can take, let him take it."
Matthew 19.12
