Sleeping with someone can certainly lead to forming an emotional bond and attachment. However, sleeping together does not automatically or necessarily create attachment in every situation. There are several factors that influence whether intimacy leads to attachment or not.
What causes attachment?
Attachment is a deep emotional bond that connects us to other people. Attachment theory suggests that we form these bonds from our earliest relationships and they influence our expectations in future relationships.
Several things can lead to forming an attachment with a sexual partner:
- Having an emotional connection prior to sex
- Regularly sleeping together over time
- Engaging in intimate foreplay and cuddling, not just sex
- Sharing personal details and building trust
- Having similarities and shared interests
- Both partners wanting more than just a sexual relationship
The more intimate the relationship, beyond just the physical act of sex, the more likely attachment is to develop.
Does casual sex cause attachment?
Purely casual sexual encounters are less likely to create significant attachment. With casual sex partners that you do not know well:
- There is less emotional intimacy and bonding
- Contact is limited to brief sexual encounters
- Details about your personal life and background are not shared
- There are no ongoing expectations for the relationship
However, some attachment can still occur in certain casual sex situations:
- If you have sex with the same casual partner regularly over time, you may begin to form a bond and expectations
- If you confide in a casual partner or share personal details, this can increase feelings of intimacy
- If one partner develops unreciprocated romantic feelings, they may become attached even if the other person does not
So while casual sex is less likely to create attachment than sex within an emotional relationship, it still can under certain circumstances.
Does sex always lead to attachment?
No, having sex with someone does not automatically or necessarily lead to attachment in every scenario. Here are some examples of when sex may not cause attachment:
- Having a one night stand with someone you just met and do not see again
- Engaging in no-strings-attached sexual friendships with little emotional intimacy
- Sex with a partner you have lost romantic feelings for but still have sex with occasionally
- Sex between couples going through separation or divorce
In these situations, sex is unlikely to increase attachment because there is little existing bond or motivation to form attachment. However, there are always exceptions. Some people may become attached after a single sexual encounter if it was very emotionally intimate.
Does greater intimacy increase attachment?
Research shows that increased intimacy during sex can facilitate attachment between partners. Behaviors leading to more intimate sex include:
- Kissing, cuddling, caressing – not just penetration
- Eye contact and face-to-face positions
- Verbal expressions of affection and appreciation
- Taking time to build arousal and not rushing intercourse
- Synchronized breathing and movement
- Adopting positions with full body contact
Studies find intimate foreplay and full-body sexual contact releases oxytocin, a hormone associated with bonding. So more intimate sex is more likely to increase attachment.
Do men and women attach differently?
Some research indicates women may release more oxytocin during sex, making them more prone to forming attachments through sex. Other studies find no significant gender differences. Both men and women can become emotionally attached through sex.
However, social expectations and gender roles do influence attachment. Women are often judged more harshly for casual sex, leading them to avoid non-committal sex. Men face less stigma and may have more casual sex with no attachment expected. But men are perfectly capable of forming attachments through intimacy if they desire a committed relationship.
Does frequency of sex impact attachment?
Couples who have sex more often tend to report higher relationship satisfaction. Frequent sex alone does not guarantee attachment, but sexual history does matter:
- The longer a couple has been sexually active, the stronger the attachment
- More frequent sex (several times a week) is linked to higher attachment levels
- Partners who have sex early in dating (within a month) form attachment faster
So while frequent sex does not automatically mean attachment will occur, regular and ongoing sex facilitates bonding.
Can you become attached after one-night stands?
It is possible but unlikely. One night stands by definition last for only one encounter. This provides limited opportunity to develop emotional intimacy. However, attachment could potentially occur:
- If you have an existing connection or romantic history with the person
- If the encounter involves substantial intimate foreplay and cuddling, not just sex
- If you exchange personal details and feel a strong mental connection
- If one partner secretly hopes the hookup will lead to more
Without ongoing contact after a hookup, any initial attachment will likely fade. Lasting bonds take time to solidify.
Does breakup sex cause attachment?
Breakup sex occurs between partners who are separating but have one final encounter. This rarely rekindles attachment. In fact, breakup sex can provide closure and make it easier to detach.
However, breakup sex could potentially re-spark feelings in some cases:
- If one partner hopes to reconcile during the encounter
- If the sex is very emotionally intimate and reminds you of your bond
- If you end up having breakup sex multiple times
- If there are unresolved feelings between you
So while not typical, it is possible for breakup sex to stir up attachment. Ongoing contact after separation usually prevents emotional detachment.
Can friends with benefits become attached?
Friends with benefits refers to friends who engage in casual, no-strings-attached sex periodically. These situations rarely lead to serious attachment:
- The focus is on sexual release not emotional intimacy
- Partners intentionally avoid romantic gestures and bonding
- The friendship provides companionship separate from the sexual encounters
However, friends with benefits do risk developing unintended attachment over time through:
- One partner desiring more than the other
- Increasingly intimate sex bringing you closer
- Spending more friend time together outside the bedroom
Clear rules and boundaries can prevent attachment in friends with benefits arrangements. But some intimacy is inevitable given the friendship basis.
Can sex lead to attachment in open relationships?
Open relationships refer to committed couples who agree to engage in sex outside their partnership. Most open relationships have rules preventing emotional intimacy and attachment with casual partners. Guidelines may include:
- No spending the night or vacations with casual partners
- No dating-type activities like dinners out or cuddling after sex
- Strictly sexual encounters focused on physical pleasure
- Using protection to maintain emotional distance
However, attachment can still develop if:
- Rules are broken due to cheating or deception
- You repeatedly hookup with the same outside partner
- Your partner objects to a particular casual relationship
Healthy open relationships require excellent communication, honesty and boundaries to prevent unwanted attachment.
Do couples become more attached over time?
Research shows attachment strengthens the longer a couple stays together. Reasons long-term couples attach more include:
- Sex becomes more comfortable, intimate and fulfilling
- Couples become dependent on each other’s emotional support
- Shared memories, children and assets connect you
- Love and commitment deepen through weathering challenges
So while sparks fade in some long-term relationships, emotional attachment typically grows stronger over decades spent together. Shared sexual history plays a role in cementing attachment.
Can you become attached after rebound sex?
Rebound sex occurs shortly after ending a relationship, before you have had time to process the breakup. This often represents a reflex reaction to pain or loneliness. Purely physical rebound sex without intimacy rarely leads to lasting bonds.
Attachment is more likely if:
- You have an existing emotional connection with the rebound partner
- You project feelings about your ex onto a new partner
- You use sex to try filling the void left by your ex
- You lack self-awareness and jump into another commitment too quickly
Healthy rebound sex serves as an erotic distraction without attachment. Be cautious about misreading post-breakup emotions as attachment.
Do long distance relationships struggle with attachment?
Physical separation challenges attachment in long distance relationships. Without regular in-person contact, couples may struggle to maintain intimacy.
Factors that can weaken attachment in long distance relationships include:
- Less frequent sex leading to disconnection
- Difficulty interpreting emotions from a distance
- Loneliness and jealousy due to being apart
- Life experience gaps opening up over time
However, long distance couples can take measures to preserve attachment across the miles:
- Communicating frequently through visits, calls, texts
- Maintaining sexual intimacy through sexting, video sex, photos
- Planning romantic reunions and concrete plans to close the gap
- Reassuring your partner often and sharing date nights remotely
Long distance requires concerted effort but does not preclude meaningful attachment. Virtual intimacy can sustain bonds until couples reunite.
Is sex the only way to build attachment?
No, sex alone does not create attachment if the relationship lacks sustained emotional intimacy. Non-sexual activities also foster bonding, like:
- Casual dating focused on conversation and activities
- Cuddling, kissing, massage and affection without intercourse
- Cooking meals, exercising, traveling together
- Supporting each other through challenges and obstacles
- Laughing, inside jokes and genuine friendship

| Type of Sexual Encounter | Likelihood of Attachment |
|---|---|
| One night stand | Low |
| Friends with benefits | Moderate |
| Rebound sex | Low |
| Breakup sex | Very Low |
| Open relationship hookup | Low |
| Long-term relationship sex | High |
| Intimate, romantic sex | High |
This table summarizes the typical potential for different types of sexual experiences to facilitate emotional attachment between partners.
Can sex complicate platonic friendship?
Having sex with a platonic friend can certainly complicate the friendship, but does not necessarily ruin it. Potential issues that may arise include:
- One friend desiring an ongoing sexual relationship
- Jealousy if one friend dates others
- Unreciprocated romantic feelings developing
- Awkwardness or tension after a negative sexual experience
Clear communication is key for preserving the friendship. Both partners should agree the sex was a one-time occurrence and set boundaries going forward. Valuing the platonic friendship can help couples move past a sexual slip-up.
Do sexual fantasies increase attachment?
Harboring intense sexual fantasies about someone does not necessarily mean you will develop an attachment with them. Reasons fantasies may not translate to real attachment include:
- Fantasies idealize people’s bodies or personas, which rarely match reality
- You may fantasize about celebrities or strangers you will never meet
- Sharing fantasies requires vulnerability most are uncomfortable with
- Some prefer fantasies to remain private and not acted upon
However, if fantasies about someone are romantic rather than just sexual, this can reflect a desire for emotional closeness that could potentially lead to attachment if reciprocated.
Conclusion
While sex can certainly foster emotional and psychological attachment between partners under the right circumstances, it does not automatically or necessarily lead to bonding in all cases.
Whether sex results in attachment depends on the larger context of the relationship. Strong existing emotional intimacy, romantic interest from both parties, regularly engaging in vulnerable sex, demonstrating care for your partner – these behaviors are more likely to pave the way for attached, committed bonds. Without sustained emotional investment outside the bedroom, sex alone provides momentary pleasure but no guarantee of long-term attachment.
