Exactly! And I am convinced it pleases God for us to be married and have sex.
Gen 2:24 Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
Our Lord also said:
Matthew 19:10-12
Douay-Rheims 1899 American Edition (DRA)
His disciples say unto him: If the case of a man with his wife be so, it is not expedient to marry. Who said to them: All men take not this word, but they to whom it is given. 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.
And, Saint Paul wrote:
1 Corinthians 7:1
Douay-Rheims 1899 American Edition (DRA)
7 Now concerning the thing whereof you wrote to me:
It is good for a man not to touch a woman.
1 Corinthians 7:8
Douay-Rheims 1899 American Edition (DRA)
But I say to the unmarried, and to the widows: It is good for them if they so continue, even as I.
1 Corinthians 7:24-26
Douay-Rheims 1899 American Edition (DRA)
Brethren, let every man, wherein he was called, therein abide with God. Now concerning virgins, I have no commandment of the Lord; but I give counsel, as having obtained mercy of the Lord, to be faithful.
I think therefore that this is good for the present necessity, that it is good for a man so to be.
1 Corinthians 7:32-35
Douay-Rheims 1899 American Edition (DRA)
But I would have you to be without solicitude. He that is without a wife, is solicitous for the things that belong to the Lord, how he may please God.
But he that is with a wife, is solicitous for the things of the world, how he may please his wife: and he is divided. And the unmarried woman and the virgin thinketh on the things of the Lord, that she may be holy both in body and in spirit. But she that is married thinketh on the things of the world, how she may please her husband. And this I speak for your profit: not to cast a snare upon you; but for that which is decent, and
which may give you power to attend upon the Lord, without impediment.
Scripture is also clear that some are called, not to be married, but to serve the Lord alone. Our Lord was alone, and Priests sit
in persona Christi, and so their
discipline is to remain celibate. This is consistent with
Matthew 16:24 and
Luke 9:23 in which we are to deny ourselves, take up our crosses, then follow Jesus. For some, that cross is the single life.
