Purpose: This study explored how partners/spouses of people with Spinal Cord Injury (SCI) experienced intimacy, sexual function, and sexual satisfaction post-SCI., Materials and Methods: Qualitative, semi-structured interviews were conducted with the partners/spouses of people with SCI living in the community in the United Kingdom. Twelve participants (7 females; 5 males) were recruited using purposive sampling. A nine-item semi-structured interview design was used. Interviews were transcribed verbatim and analysed via Interpretative Phenomenological Analysis (IPA)., Results: Three superordinate themes were demonstrated: (1) Stolen sex through unpreparedness; (2) Redefining sex; and (3) Compromised commitment. Partners struggled to come to terms with the shock of radically altered post-SCI sexual relationships, questioning how their changed sexual relationship and sexual identity conflicted with caring requirements. To minimise post-SCI relationship changes, some partners engaged in strategies to protect against, distract from and avoid sexual intimacy, whereas others were able to retain adapted pre-injury patterns of intimate behaviour., Conclusion: Compromised sexual function and satisfaction significantly disrupt relationship dynamics post-SCI, initiate voluntary celibacy, and limit the perceived viability of continued sexual intimacy. Specialist partner-support provisions are urgently needed, recognising that partner support needs are not restricted to the inpatient rehabilitation phase but importantly extend long past discharge into the community.
