Matthew 19:11-12

But he said unto them, All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother’s womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven’s sake. He that is able to receive it, let him receive it.

This is Matthew 19:11-12. What did Jesus mean by this? In particular what did he mean by those who make themselves eunuchs for the kingdom of heaven's sake? Catholics think it is the conscious choice for celibacy. Perhaps. Would this blessing not be available to the married? I contend that it can be and even to married couples who enjoy intimacy. 

Remember that a eunuch as a servant who protects his master's harem so that only the master can pass on his seed. So in the sense that a man makes sure that only God's word (seed) is passed on to others, then he becomes a eunuch for the kingdom of heaven. But while this may have some validity it is too universal to apply in the context of a discussion of marriage. Every man is called to be so faithful to God's word that he does not pollute it with his own word.

Men and women have liberty in marriage to have sexual satisfaction for its own sake. But when they choose to elevate their relationship so that sexual satisfaction is no longer a self serving object of the marital relationship they become eunuchs for the kingdom of heaven's sake.
