7 Surprising Relationship Habits That Build Trust and Intimacy

One in Three People Do These 7 Surprising Things in Their Relationships

Relationships are rarely as picture-perfect as the highlight reels on social media. Beneath the surface, even the happiest couples harbor habits that outsiders might find odd, unnecessary, or even embarrassing. But studies and relationship experts agree: these quirky behaviors are often indicators of comfort, trust, and emotional intimacy. In fact, one in three people admits to practicing these surprising habits in their relationships—and you probably do too, even if you’ve never discussed them with anyone else.

Introduction: Embracing the Strange Side of Love

Couples become comfortable enough to let their guards down, showing sides of themselves that the rest of the world rarely sees. Far from being problematic, these behaviors form the backbone of intimacy. Shared quirks, bizarre requests, and playful habits—while seemingly weird—demonstrate just how close partners can become. This article explores seven surprising things that couples commonly do and explains why embracing them can make your relationship stronger.

1. Asking Your Partner for Gross Body Checks

If you’ve ever asked your partner, “Can you check my back for weird spots?” or “Is this bug bite normal?”, you’re far from alone. A significant portion of couples regularly exchange these kinds of requests:

• Booger checks—Yes, it’s common for partners to ask each other to check for boogers before leaving the house.
• Inspecting rashes, ingrown hairs, or blackheads.
• Discussing digestive issues—Conversations about poop, gas, or stomach troubles become normalized between close partners.

While it feels unglamorous, these exchanges are a sign of deep trust. Being able to disclose body concerns without embarrassment—especially ones you wouldn’t admit to friends—signals high comfort and belonging within the relationship.

2. Speaking in a Secret Nonsense Language

As couples spend more time together, their communication style evolves:

• Inventing code words for everyday items, like “the thingy with the stuff” instead of a spatula or remote control.
• Unique inside jokes that only you and your partner understand.
• Referencing shared experiences with a single word, look, or gesture.

Researchers and therapists say developing a “private language” is a sign of intimacy. Such code words and signals demonstrate emotional closeness and create a sense of exclusivity—a private world apart from everyone else. Couples often giggle over phrases that outsiders would find nonsensical, but for them, it’s the glue that keeps their bond strong.

3. Teasing and Playful Weirdness

Couples who tease each other—whether it’s about a quirky habit, an eccentric outfit, or a silly mistake—aren’t just being mean. Teasing, when done with kindness and respect, fosters light-heartedness, diffuses tension, and helps partners reconnect after disagreements. Examples include:

• Making playful jokes about each other’s quirks.
• Pretending to be silly characters or animals.
• Engaging in tickle wars or mock arguments.

Laughter is a proven tool for repairing conflict and boosting relationship satisfaction. Playful interactions remind partners why they enjoy each other’s company even in difficult times.

4. Flirting Like You Just Met

Even after months or years together, keeping flirtation alive is crucial:

• Complimenting attractiveness—Noticing when your partner looks beautiful, handsome, or even “extra hot.”
• Physical playfulness—A gentle pinch, silly dance, or an exaggerated “ooh la la” when your partner undresses.
• Sending flirty or suggestive texts throughout the day.

Research shows that sexual energy doesn’t have to fizzle just because a relationship matures. In fact, commenting on yourpartner’s looks and keeping flirtatious energy alive outside the bedroom helps sustain desire and maintains the romantic spark.

5. Sharing Annoyances and Weird Thoughts

Venting minor irritations is normal—and, in healthy relationships, can be constructive:

• Complaining about small annoyances, like leaving socks on the floor or forgetting to do chores.
• Checking in on emotional states—”Are you okay?” “Did something upset you today?”
• Talking openly about moods or stress.

Regularly expressing what’s on your mind—good or bad—shows that you trust your partner enough not to hide your feelings. It helps avoid misunderstandings and builds emotional support.

6. Entering Each Other’s Private Spaces

As couples merge their lives, privacy boundaries relax:

• Sharing bathrooms or getting ready together.
• Borrowing personal items without asking—deodorant, phone charger, even clothes.
• Comfortably existing in the same room in silence.

This comfort level is not just about sharing space but also respecting each other’s solitude. Partners who can coexist quietly, or even finish each other’s sentences, demonstrate a mature kind of love that values both unity and independence.

7. Checking In on Each Other’s Emotional State

Healthy couples make it a routine to check in emotionally:

• Daily emotional check-ins—”How are you feeling today?”
• Encouraging partners to share anxieties, fears, or stresses.
• Offering support during tough times, celebrating wins and comforting losses.

Maintaining emotional transparency ensures both partners remain attuned to each other’s needs and can react supportively. This habit not only keeps misunderstandings at bay but also deepens trust and emotional resilience.

Why These Habits Matter

Every couple develops routines that, to outsiders, may seem silly, gross, or unnecessary. But beneath these quirks lies something essential:

• Trust and Vulnerability: Sharing the less glamorous aspects of life and body with a partner—without fear of judgment—builds a solid foundation of trust.
• Playfulness: Silly games, inside jokes, and lighthearted teasing help couples stay connected and navigate rough patches.
• Emotional Connection: Checking in, sharing honest feelings, and supporting each other through emotional ups and downs helps maintain a healthy bond.
• Communication: Discussing everything from boogers to bad moods establishes openness that is vital for long-term happiness.
