How can fetishes affect a relationship?

The way fetishes are understood has shifted over the past fifty years, with sexual diversity becoming more widely accepted. This article explores current thinking about fetishes and how they can affect relationships, both emotionally and practically.

A fetish typically involves sexual arousal or pleasure associated with a particular object, body part or activity. Kink is a broader term for sexual interests or activities that fall outside what society might consider 'typical'. BDSM (bondage and discipline, dominance and submission, sadism and masochism) is one form of kink, in which power and/or sensation are eroticised as a route to arousal and satisfaction.

It’s hard to know how many people engage in fetishes and kinks. However, Holvoet et al. (2017) found that 46.8% of respondents reported engaging in at least one BDSM-related activity, suggesting that these interests may be more common than previously assumed.

Stigma and shame around fetishes

One challenge people with fetishes or BDSM interests may face is stigma. People with fetishes or BDSM interests might be acutely aware of how others might see them, and this can have a profound psychological impact. Internalised shame and guilt can stem from social disapproval, especially when someone feels they must keep their interests secret. Secrecy can worsen distress, and it can also stop people from seeking support.

Some people may have experienced healthcare professionals assuming that BDSM is inherently abusive or linked to unresolved trauma. This assumption can pathologise consensual and healthy sexual expression, leaving people feeling judged in the very place they hoped to feel understood.

Navigating fetishes in a relationship

Within a relationship, this fear of judgement or rejection might lead someone to hide their desires. Over time, this can lead to emotional distance, reduced trust, and a quiet sense of dissatisfaction, as one partner feels unable to be fully themselves. The partner may sense something is being held back without knowing what, and may feel shut out or insecure.

How an interest is shared matters too. If a fetish is introduced abruptly or insensitively, the other partner may feel pressured, inadequate, or objectified. They may then feel guilty for not sharing the interest, while the partner who disclosed feels rejected or ashamed for having spoken up. Neither person is doing anything wrong, but both can end up feeling hurt and misunderstood. Differences in sexual interest are common in relationships, and what makes them difficult is often the silence and assumptions around them rather than the difference itself.

Difficulties can also arise when a fetish becomes the main route to arousal. The other partner may feel neglected, invisible, or reduced to an object, for example, if the focus is on a body part or item of clothing rather than on the whole person. This can undermine intimacy and a sense of being wanted for who you are.

How can fetishes strengthen a relationship?

Engaging in fetish or BDSM practice requires open, honest, and ongoing communication. In BDSM communities, negotiation and consent are fundamental, and consent is understood as both informed and revocable. Partners often agree on boundaries in advance, including limits and safe words, and check in with each other afterwards.

These conversations about boundaries, fantasies, fears, and desires can deepen trust and emotional intimacy, often well beyond the bedroom. Research suggests that couples who share novel and exciting activities may experience greater relationship satisfaction.

For many people, kink offers a structured way to explore vulnerability, power, and trust safely. A submissive partner may explore surrender and trust, gaining emotional insight into their attachment patterns, while a dominant partner may experience validation through responsible care and leadership. For couples who feel disconnected, shared rituals or intentional play can reintroduce passion and purpose, particularly when approached mindfully.

Community involvement can also offer belonging, education, and support. This can be especially valuable for people who are gender, sexual, erotic, or relationally diverse (GSERD). Some survivors of sexual trauma report that consensual kink can help them regain a sense of agency and bodily autonomy. Research involving autistic adults who engage in kink has also suggested that the clarity and structure of negotiated power can feel reassuring for some people.

The role of psychosexual therapy

Many people exploring these aspects of their sexuality may never have spoken about them aloud. Psychosexual therapy offers a confidential, non-judgemental space to do so, whether you attend alone or with a partner.

For an individual, therapy can help to explore where feelings of shame or fear come from, separate a sexual interest from the stigma attached to it, and build confidence in understanding what you want and why. For someone who has felt dismissed or pathologised in the past, it can also be a chance to feel heard without assumptions.

For couples, a therapist can help partners find language for conversations that feel too difficult to start at home. Each person can express their needs, anxieties, and limits, and be heard. This is particularly helpful where one partner feels rejected or pressured, or where interests differ and the couple feels stuck.

Therapy does not aim to push anyone towards a particular practice. Instead, it supports partners to understand each other, explore options at a pace that feels safe for both, and agree on what works for them, which may include compromise or choosing not to pursue something. Where intimacy has suffered through secrecy, resentment, or an experience that left someone feeling hurt or unsafe, therapy can also help rebuild trust and closeness.

Fetishes are increasingly recognised as part of the diverse spectrum of human sexuality. In a relationship, they can be a source of both conflict and connection, depending on communication, consent, and shared values. When partners communicate openly, respect each other's boundaries, and prioritise consent, fetishes and kink can enhance intimacy, trust, and connection.

When secrecy, shame, or coercion are present, any sexual interest, conventional or not, can become a source of pain. Healthy relationships are built on understanding, respect, and genuine consent. If a fetish or difference in desire is causing distress in your relationship, support is available, and you don't have to work through it alone.
