I happened to see this thread when I posted a picture about hunkering down. I don't have a family so-to-speak, so don't frequent this forum except occasionally if I find something that might help younger people from my life's experience. Us folks from the 70's have a lot to offer from life experience. Life is a sacred experience and a good teacher.
The Bible says many things about intimacy between a man and woman. Same sex intimacy is not allowed in the Bible for many reasons. It sounds like the OP is eluding to the Catholic church about procreation being the main reason for marital intimacy. The Catholic church has helpful things to say about intimacy and celibacy, and many years of experience helping Christian couples.
The Apostle Paul wrote about some of these issues, but I don't have the scriptures available.
One teaching I like about the Catholic church, even though I would never go into ministry without a lady, is that they consider that Christian love, and romantic love is what marries and confirms a man and wife.
Like being born-again as a Christian, and like a baby is not born by their own efforts, a man and lady are joined in matrimony by the power of God, and their love for one another. This is a free gift. A state legal marriage is important and also a church wedding, or other Christian community gathering. Being married before church and state.
Protestants and Catholics have different approaches to marriage and divorce, and procreation and celibacy.
Even Paul said he wanted a wife, but he was a traveling evangelist who suffered greatly for the faith and did not want to subject a woman to such a difficult life.
The Catholic church, from what I understand, will grant an annulment if they determine that a "sacramental" marriage was not happening for various reasons. And in other cases, even if a couple were married only by state and not church, if they were "married" by love, they may not grant an annulment. Even state courts require valid reasons for divorce.
Sexuality and sexual intimacy has an emotional and spiritual impact on a couples life.
Marriage must be voluntary and confirmed by God.
It is a serious commitment, and should not be rushed into, like myself and my ex-wife did, and we both learned from the experience, but also suffered consequences similar to emotional trespassing, which is referred to in psychology as "emotional boundaries," even though we were both kind of clueless as to what we were getting into. Couples are still responsible for positive and negative consequences of relationships. Babies happen. I'm an unplanned one myself.
Young people should realize that there are medical dangers to intimacy, as well as emotional and spiritual hazards. Persistent unhealthy lifestyles can lead to emotional wounds. Love is powerful.
There is a popular song having the words, "Heaven opens up the door, where angels fear to tread." I believe this is from the Bible.
Paul said that just because as Christians we are covered by the New Covenant of Grace, this does not give us license to do as we please without accountability and taking responsibility.
Somewhere in the Old Testament, it says, "Guard your hearts."
But, God is a merciful savior and healer of hearts.
Never despair of making mistakes and feeling overwhelmed.
Feelings do not create reality, and may or may not reflect true spirituality.
Like John the evangelist said: "If our hearts condemn us, God is greater than our hearts and knows all things."
A spirit of conviction, that motivates people to make changes and turn to God, is from the Holy Spirit. This is different than a spirit of condemnation, which does not come from God and should be dismissed and ignored since it is a deceiving spirit - the spirit of depression being one form of it.
That's the serious side of what the OP started.
I think she was also using a bit of melodramatic reverse psychology?
NO. If a couple can not have children, they might still consider marital intimacy.
But, they might want to run it by their pastor, or a bishop.
I'm not trying to be light-hearted about a serious subject, and the Bible says to "work out our salvation in fear and trembling."
But, it also says to spice up our fellowship as a way of reaching out to people and that, "the joy of the Lord is our strength."
One pastor who knew how to do this without speaking beneath his calling, pastor Steve, told the story about a monk centuries ago who was working in the basement of a monastery for many years alone writing out with a pen the Bible.
One day his brother monks heard him exclaim very loudly...
"OH NOOO....IT SAYS CELIBRATE!!! NOT CELIBATE!!
This has a good message for those who are not called to a life of celibacy. And those who are will receive a noble reward in Heaven for living out the Bible in humble service of the Lord.
But celibacy can work under the right conditions, for those who are called, as Paul said. It's a very powerful way of ministry for those who are called and can make it work out.
This next story is more fitting for college level about the consequences of not obeying the Bibles instructions to "leave home and find a spouse of the opposite sex."
A college student, a male student, was in class and taking a long grueling college test. The student, with an attitude, wanted to express a hypothetical situation, (this means he wasn't serious) said that, "But, what if I was awake all night, partying and having sex all night and I'm too worn out for such a grueling test."
The college professor, a lady, said:
"Well, Mr. Smith, I guess you will just have to write with your other hand...."
