Question on asexuality

Because one of the purposes of marriage is to avoid sexual immorality (1 Corinthians 7:2, 9), those who lack sexual desires can find the single life to be good and appropriate for them.  The apostle Paul recognized that he had been “gifted” (1 Corinthians 7:7) to lead a celibate life, and he considered that to be advantageous for his ministry.

Our Catechism’s explanation of the Sixth Commandment is that “We should fear and love God that we lead a pure and decent life in words and actions, and that husband and wife love and honor each other.”  Those who lack sexual desires might also, like the apostle, think of their situation as a gift, since they would likely not struggle as much with the temptation to break this commandment as others might.
