That idea sounds catchy because it points to something real—but it oversimplifies the problem in a way that can actually make relationships worse.
Sex can absolutely help a marriage, but it’s not a universal fix—and treating it like one misses what’s actually going on underneath.
Why it sometimes feels true
Regular sex can:
- Increase bonding through hormones like oxytocin
- Reduce stress and tension
- Create a sense of closeness and reassurance
So in relationships where the core is already healthy, more physical intimacy can smooth over minor friction. That’s why the statement can feel “true” in certain cases.
Where it breaks down
Most serious relationship problems aren’t caused by a lack of sex. They usually come from:
- Resentment that hasn’t been addressed
- Poor communication or feeling unheard
- Mismatched expectations about roles, effort, or priorities
- Loss of emotional connection
If those exist, pushing for more sex often amplifies the problem instead of solving it. One partner may feel:
- Used rather than understood
- Pressured rather than desired
- Disconnected rather than closer
At that point, sex stops being bonding and starts becoming another source of tension.
The direction actually runs the other way
In most long-term relationships, the pattern is:
Emotional safety → trust → desire → satisfying sex
Not:
More sex → fixes emotional problems
When people feel respected, understood, and valued, sexual connection tends to follow naturally. Without that foundation, frequency doesn’t create intimacy—it can highlight its absence.
The power dynamic issue
The phrasing you used (“banging your wife’s brains out”) also hints at a one-sided, performance-focused view of sex. Healthy sexual connection in a marriage is:
- Mutual
- Responsive to both partners’ needs
- Based on consent, comfort, and emotional attunement
When it becomes something one partner is supposed to do to fix things, it can shift into pressure or imbalance, which erodes trust over time.
What actually helps most marriages
The strongest predictor of relationship satisfaction isn’t sexual frequency—it’s how couples handle conflict and connection day-to-day. Research from John Gottman shows that things like:
- Feeling heard and respected
- Repairing conflicts quickly
- Maintaining small daily moments of connection
matter more consistently than how often a couple has sex.
A more accurate version of the idea would be:
A good sexual connection can support a healthy relationship—but it can’t replace communication, respect, or emotional closeness.
If those deeper pieces are in place, sex often improves on its own. If they’re not, increasing frequency alone won’t fix what’s broken.
