No. However Paul does seem to say that it is better to marry than to burn. I Corinthians 7:9.
What do you think are the characteristics of a celibate man? Does it mean he has no desire for the opposite sex or sex at all?
Celibacy is interior self offering to God. A person who is celibate commits him/ or herself to Christ alone and vows to God. Celibacy itself is not limited to the clergy. In the early days of Christianity, there were virgins who committed themselves to Jesus like St. Celicia who refuse to marry a pagan from an arrange marriage because she confesses that her true spouse is Jesus Christ.
It is not desire for sex. Desire for sex brings sinful thoughts of lust. It is bodily pleasure. However, sexual intercourse is not dirty. Sexual intercourse only have one function, pro-creation. Sex is not use for pleasure or self-gratification. To view sex as such reduces the person’s humanity as a mere toy, like dildo. Humans beings are not toys for seeking pleasures.
The Catechism states:
2349 "People should cultivate [chastity] in the way that is suited to their state of life. Some profess virginity or consecrated celibacy which enables them to give themselves to God alone with an undivided heart in a remarkable manner. Others live in the way prescribed for all by the moral law, whether they are married or single."136 Married people are called to live conjugal chastity; others practice chastity in continence:
There are three forms of the virtue of chastity: the first is that of spouses, the second that of widows, and the third that of virgins. We do not praise any one of them to the exclusion of the others. . . . This is what makes for the richness of the discipline of the Church.
On the issue of Sex, the Catholic Church teaches the following as well:
2360 Sexuality is ordered to the conjugal love of man and woman. In marriage the physical intimacy of the spouses becomes a sign and pledge of spiritual communion. Marriage bonds between baptized persons are sanctified by the sacrament.
2361 "Sexuality, by means of which man and woman give themselves to one another through the acts which are proper and exclusive to spouses, is not something simply biological, but concerns the innermost being of the human person as such. It is realized in a truly human way only if it is an integral part of the love by which a man and woman commit themselves totally to one another until death."143
Tobias got out of bed and said to Sarah, “Sister, get up, and let us pray and implore our Lord that he grant us mercy and safety.” So she got up, and they began to pray and implore that they might be kept safe. Tobias began by saying, “Blessed are you, O God of our fathers. . . . You made Adam, and for him you made his wife Eve as a helper and support. From the two of them the race of mankind has sprung. You said, ‘It is not good that the man should be alone; let us make a helper for him like himself.’ I now am taking this kinswoman of mine, not because of lust, but with sincerity. Grant that she and I may find mercy and that we may grow old together.” And they both said, “Amen, Amen.” Then they went to sleep for the night.
2362 “The acts in marriage by which the intimate and chaste union of the spouses takes place are noble and honorable; the truly human performance of these acts fosters the self-giving they signify and enriches the spouses in joy and gratitude.”
Sexuality is a source of joy and pleasure:
The Creator himself . . . established that in the [generative] function, spouses should experience pleasure and enjoyment of body and spirit. Therefore, the spouses do nothing evil in seeking this pleasure and enjoyment. They accept what the Creator has intended for them. At the same time, spouses should know how to keep themselves within the limits of just moderation.
2363 The spouses’ union achieves the twofold end of marriage: the good of the spouses themselves and the transmission of life. These two meanings or values of marriage cannot be separated without altering the couple’s spiritual life and compromising the goods of marriage and the future of the family.
The conjugal love of man and woman thus stands under the twofold obligation of fidelity and fecundity.
