Sexual attraction runs on some of the brain’s most powerful reward circuitry, which means you cannot simply decide to stop feeling it the way you decide to stop eating chips. What you can do is understand why the pull feels so strong, avoid the habits that accidentally intensify it, and adopt strategies that genuinely weaken it over time. The process has more in common with breaking a behavioral habit than with flipping a switch, and some popular approaches, like forcing yourself not to think about the person, reliably make things worse.
Why Attraction Feels Impossible to Override
Sexual and romantic attraction activates the same neural reward pathways involved in motivation, craving, and even substance dependence. Key brain regions include the ventral tegmental area and the nucleus accumbens, and the chemical messengers doing much of the work are dopamine, norepinephrine, and cortisol, along with shifts in serotonin activity.1PubMed Central. The neuroendocrinology of love Dopamine, in particular, is the molecule your brain uses to tag experiences as rewarding and worth repeating. When you are attracted to someone, even thinking about them can trigger a small dopamine release, reinforcing the mental habit of thinking about them more.
This is not a design flaw. It is one of the oldest motivational systems in the mammalian brain, built to push organisms toward reproduction. The downside is that it does not care whether the attraction is convenient, reciprocated, or healthy. It operates below conscious intention, which is why telling yourself “just stop thinking about them” feels about as effective as telling yourself not to be hungry. The attraction is not a choice you made, and you will not undo it with a single counter-choice. But that does not mean you are powerless. The reward system responds to input: what you expose yourself to, how you direct your attention, and how much reinforcement the attraction keeps receiving.
The Thought Suppression Trap
The single most common instinct when you want to stop wanting someone is to try to push thoughts of them out of your mind. It sounds logical. The problem is that deliberate thought suppression tends to produce the opposite of what you want. Research on what psychologists call the “rebound effect” shows that actively trying to suppress a thought often leads to an increase in that thought once the effort lapses.2PubMed. God, I Can’t Stop Thinking About Sex! The Rebound Effect in Unsuccessful Suppression of Sexual Thoughts Among Religious Adolescents You spend mental energy holding the door shut, and the moment you relax, the thought floods back even stronger than before.
This has been studied specifically with sexual thoughts: people instructed to suppress sexual content experienced more intrusive recurrences afterward compared to those who were never told to suppress in the first place. The mechanism is straightforward. Suppression requires a monitoring process that constantly checks whether the unwanted thought is present. That monitoring, ironically, keeps the thought activated at a low level, priming it to resurface the moment your guard drops.
The practical takeaway is that white-knuckling your way through it, mentally repeating “don’t think about them, don’t think about them,” is one of the least effective strategies available. Alternatives that redirect attention rather than suppress it tend to fare much better, as we will get to shortly.
How Digital Contact Keeps the Cycle Going
If the person you are attracted to is someone you interact with digitally, the structure of modern communication may be working against you in ways you do not fully realize. Research on attachment and digital relationships describes how the typical patterns of texting, social media, and messaging apps can create conditions that resemble behavioral addiction cycles, particularly for people prone to anxious attachment.3PSYCHOLOGICAL JOURNAL. Anxious-Dependent Attachment in Digital Romantic Relationships: Emotional Dysregulation, Intermittent Reinforcement, and Fear of Abandonment
The core concept is intermittent reinforcement. When someone responds to your messages unpredictably, sometimes quickly and warmly, sometimes after a long silence, sometimes not at all, it creates a variable-ratio reinforcement pattern. This is the same reward schedule that makes slot machines so compelling. You never know when the next “hit” is coming, so you keep checking, keep hoping, keep feeling a jolt of dopamine anticipation every time you see a notification. Read receipts, online-status indicators, and the ability to monitor someone’s social media activity make this worse, because they give you just enough information to keep the guessing game alive without ever resolving it.
The result can look like compulsive checking of your phone, heightened anxiety during periods of silence, and an emotional roller coaster that alternates between reward (they replied!) and perceived abandonment (they haven’t replied in hours). Each cycle strengthens the attraction rather than weakening it, because the unpredictability keeps the reward system engaged. If you recognize this pattern in yourself, it points to a clear intervention: reduce or eliminate the digital channels through which the intermittent reinforcement operates. Muting, unfollowing, or blocking is not dramatic; it is the digital equivalent of removing yourself from the slot machine floor.
Redirecting Attention Instead of Fighting It
If suppression backfires, what does work? The general answer from the research on emotion regulation is attentional deployment: deliberately directing your focus toward something else rather than trying to force the unwanted thought into silence. The distinction matters. Suppression says “do not think about X.” Attentional redirection says “think about Y instead.” The second approach gives your brain something to do, which is far easier for it than doing nothing.
Neuroimaging work on attentional deployment shows that when people deliberately shift their focus away from emotionally arousing content and toward neutral or non-arousing aspects of a scene, the brain’s emotional-response centers (particularly the amygdala) actually change their activation and connectivity patterns.4PubMed Central / Springer Link. Emotion regulation and amygdala-precuneus connectivity: Focusing on attentional deployment Directing attention to non-arousing material was associated with changes in amygdala activity, while simply viewing arousing material naturally was not. The brain’s frontal regions, responsible for executive control, ramp up during the redirection, effectively helping to dampen the emotional charge.
In practical terms, this means that when a thought about the person surfaces, the most productive response is not “stop thinking that” but rather “let me engage with something else.” That might be physical activity, a conversation with a friend, a work task that requires concentration, a creative project, or even just a vivid daydream about an unrelated topic. The goal is not perfection. The thought will come back. But each time you redirect rather than suppress, you weaken the neural habit a little, and you avoid the rebound effect that would otherwise strengthen it.
Creating Physical and Digital Distance
Attraction needs fuel, and proximity is one of the most reliable sources. Every time you see the person, hear their voice, read their messages, or scroll through their photos, the reward circuitry gets another small hit. Reducing that exposure is not avoidance in a cowardly sense; it is just cutting off the supply line.
If the person is a coworker, a classmate, or someone in your friend group, total avoidance may be impractical. But you can still reduce the intensity of exposure. Sit farther away, stop initiating one-on-one conversations unless necessary, decline social invitations where they will be the center of your attention. Online, the same principle applies with even more force: mute their stories, unfollow their accounts, remove yourself from group chats where their name keeps popping up. As discussed above, the intermittent reinforcement of digital contact is one of the strongest mechanisms sustaining unwanted attraction, and it is also one of the easiest to interrupt because you control your own device settings.
People often resist this step because it feels like they are “losing” the person. But if the goal is to stop being attracted to them, maintaining full access to their digital presence while hoping the feelings will just fade on their own is like leaving dessert on your desk while trying to diet. It is technically possible to resist, but you are making it unnecessarily hard.
Time and the Natural Decline of Intense Attraction
There is a piece of good news hidden in the research on love and long-term relationships: time genuinely erodes the intensity of passionate attraction, even in relationships where the attraction is mutual and the couple stays together. Studies comparing newlywed and long-term couples find that time has a corrosive effect on the intensity of passionate love.5Interpersona: An International Journal on Personal Relationships. The Endurance of Love: Passionate and Companionate Love in Newlywed and Long-Term Marriages If even couples who are actively nurturing their connection experience this natural fade, then attraction that is not being fed by a real relationship will fade faster.
The catch is that time only works if you let it. If you are continuously re-exposing yourself to the person, replaying memories, or fantasizing about what could be, you are essentially resetting the clock. Each re-engagement gives the reward system fresh material to work with. This is why the distance and redirection strategies above matter so much: they create the conditions under which time can actually do its job. Without them, you can spend months or years in a holding pattern where the attraction never fully weakens because it keeps getting topped up.
How long does it take? There is no clean answer. It depends on how intense the attraction was, how much contact you maintain, whether the attraction was tied to a real relationship or was always one-sided, and your own temperament. But most people who genuinely reduce contact and redirect their attention report meaningful improvement within a few months, not years.
Leaning on Your Social Circle
Talking to friends or trusted people about what you are going through is not just emotionally comforting; it may have a measurable physiological effect. Research on social support and stress shows that receiving support from others can dampen the body’s stress response, reducing cortisol levels and attenuating the anxiety and negative emotions that accompany stressful situations.6PubMed Central. Relations between plasma oxytocin and cortisol: The stress buffering role of social support Baseline oxytocin, a hormone associated with bonding and trust, was inversely related to cortisol and feelings of distrust in that research.
Unwanted attraction is stressful. It can produce anxiety, shame, rumination, and a sense of being out of control. Social support helps on multiple levels: it gives you an outlet for the emotional pressure, it provides external perspective (friends are remarkably good at seeing what you cannot), and it activates bonding chemistry that partially competes with the attraction-related chemistry dominating your mental landscape. You do not need to confess every detail. Even spending more time with people who make you feel grounded and valued can shift the emotional balance away from the obsessive pull of the attraction.
Do Medications Reduce Attraction?
A common belief is that antidepressants, particularly SSRIs, blunt romantic and sexual feelings so thoroughly that they could serve as an unofficial remedy for unwanted attraction. SSRIs do frequently reduce libido and sexual function as a side effect, and that much is well documented. But the picture with romantic attraction specifically is less clear than popular wisdom suggests.
A study of young adults experiencing romantic love found that SSRI use was not significantly associated with the intensity of romantic love, obsessive thinking about a loved one, commitment, or sexual frequency.7Journal of Affective Disorders. SSRI use is not associated with the intensity of romantic love, obsessive thinking about a loved one, commitment, or sexual frequency in a sample of young adults experiencing romantic love In other words, people on SSRIs were not thinking about their romantic interest less often or with less intensity than people not on SSRIs, even though SSRIs are known to affect serotonin systems involved in both mood and attraction.
This does not mean SSRIs have zero effect on anyone’s romantic feelings. Individual responses to medication vary widely, and some people do report feeling emotionally “flattened” on SSRIs in ways that include reduced romantic intensity. But it does mean that starting or adjusting psychiatric medication specifically to suppress an unwanted attraction is not a reliable strategy, and it carries its own side effects and risks. If you are already on an SSRI for depression or anxiety, it may or may not have any effect on your attraction to a specific person. Medication decisions should be driven by mental health needs, not by romantic frustration.
When the Attraction Involves Someone Off-Limits
Much of the anguish around unwanted attraction comes from the specific context: you are drawn to a friend’s partner, a coworker you report to, an ex you know is bad for you, or someone who is simply not available. The attraction itself is not a moral failing. Feelings arise involuntarily. What matters is behavior.
If the person is an ex, the intermittent reinforcement problem can be especially severe. Breakups rarely produce clean breaks in the age of social media, and every accidental glimpse of their new life can re-trigger the reward-anticipation cycle. A full digital separation, even if temporary, tends to accelerate recovery dramatically compared to the “we can still be friends and follow each other” approach.
If the person is someone you see regularly at work or in a social group, you face a harder version of the same challenge. You cannot eliminate exposure, but you can minimize one-on-one time, avoid confiding in them about personal matters (emotional intimacy deepens attraction), and mentally reframe your interactions as strictly functional. Some people find it helpful to deliberately notice the person’s flaws or incompatibilities, not in a mean-spirited way, but as a corrective to the idealization that attraction tends to produce. The brain in attraction mode edits out the mundane and magnifies the appealing. Consciously reminding yourself of the full, unedited picture can take some of the shine off.
Novelty, Habituation, and Why New Experiences Help
Animal research has long documented a phenomenon where sexual interest in a familiar partner declines over repeated encounters but can be temporarily renewed by the introduction of a novel partner.8PubMed. Copulation and ejaculation in male rats under sexual satiety and the Coolidge effect This is called the Coolidge effect, and while the human version is more nuanced, the underlying principle is relevant: novelty activates the dopamine reward system. When your brain is fixated on one person, it is partly because that person represents the most salient source of novelty and reward in your environment.
Introducing new sources of stimulation and engagement can help break the fixation. This is not about rushing into a rebound relationship or forcing yourself to date before you are ready. It is about giving your reward system something new to chew on. Travel, new hobbies, new friendships, physical challenges, creative work, and unfamiliar environments all generate novelty signals. They do not erase the attraction overnight, but they gradually widen the aperture of what your brain pays attention to, making the one person a smaller fraction of your mental landscape rather than dominating it.
People who stay in highly routine environments while nursing an unwanted attraction tend to have a harder time because the person remains the most interesting thing in their world. Shaking up your routines is not a distraction technique; it is actively providing the kind of stimulation that loosens a fixation’s grip.
Therapy and Professional Support
If an unwanted attraction is consuming a significant part of your day, interfering with your ability to work or maintain other relationships, or causing you real distress over a period of months, a therapist can help in ways that self-help strategies sometimes cannot. Cognitive-behavioral approaches can target the specific thought patterns and behavioral loops keeping the attraction alive. A therapist can also help you identify whether the attraction is partly driven by unmet needs, attachment patterns, or unresolved issues from past relationships, information that makes it much easier to address the root cause rather than just managing the symptom.
This is especially worth considering if you notice a pattern: if you repeatedly develop intense, consuming attractions to unavailable people, the issue may not be about this one person at all. It may reflect an attachment style or relational pattern that therapy is well suited to address. The attraction is the surface. What sits underneath it determines whether removing this person from the equation actually resolves anything or just shifts the fixation to the next unavailable person who comes along.
