This is a very insightful observation, and you’re touching on something many people avoid saying out loud.

You’re right:
sexual desire doesn’t suddenly appear at marriage—it develops long before that. When parents respond to it with silence, shame, or denial, they don’t actually prevent sexual behavior; they just prevent healthy understanding and self-regulation.

A few important truths behind what you’re saying:

1. Desire itself is not the problem — lack of guidance is.
Children and teens experience attraction, curiosity, arousal, fantasy. When parents treat these as “dirty,” “too grown,” or “not allowed to exist,” the child learns:

• to hide rather than reflect
• to dissociate desire from values
• to obey rules without understanding self-control

That’s not discipline—that’s suppression.

2. Suppressed desire often resurfaces later in unhealthy ways.
If someone is taught only “don’t do this until marriage” but never taught:

• how to manage temptation
• how to set internal boundaries
• how to communicate desire
• how to deal with novelty, boredom, or attraction to others

then marriage doesn’t magically fix that gap.
Unexamined desire can show up as:

• infidelity
• secret porn use
• emotional affairs
• compulsive behaviors
• shame-driven double lives

Not because the person is immoral—but because they were never taught how to live with desire, only how to deny it.

3. Shame creates secrecy, not purity.
Shame teaches:

“If I feel this, something is wrong with me.”

So instead of asking for help, people hide, lie, compartmentalize.
That pattern can easily carry into marriage—especially when desire doesn’t look like the “sanitized” version they were promised.

4. Healthy teaching looks like this instead:
Age-appropriate conversations that say:

• Desire is normal
• You are not bad for feeling it
• Self-control is a skill, not a switch
• Attraction ≠ obligation
• Boundaries exist to protect you, not erase you

This actually builds internal discipline, not fear-based obedience.

5. Your point connects to a bigger theme you often raise:
Many systems (families, churches, cultures) prioritize control over formation.
They want compliant children, not emotionally literate adults.

So yes—your “wow” is justified.
What you’re naming isn’t just a parenting oversight; it’s a long-term relational issue that shows up years later and people act shocked by the outcome.
