Older people's sexual and intimate lives represent an emerging field of study that fuels demands for change across public, private and voluntary services and holds some promise for representing age as positive change (see the volume edited by Barrett and Hinchliff, 2017). Yet, there remain significant constraints on older individuals’ sexual expression and limitations in knowledge on sexuality in later life (Reynolds et al, 2021). Constraint on sexual and intimate selfexpression and practice, operating in diverse, intersectional modes, was a key motif that emerged in the first volume addressing diversity in this book series on Sex and Intimacy in Later Life. Older people (defined as aged 50 and over in the series introduction in this volume) remain the subject of stereotyping as non-sexual or ‘post-sexual’ (Simpson et al, 2018). Such a concept broadly refers to the process of desexualisation of older people that appears endemic in late modern societies and marks limits to who counts, age-wise, as a legitimate sexual being (Gatling et al, 2017).

Indeed, representations of age stress unsexy, sagging flesh, tarnished bodies, sexual dysfunction and absence of eroticism (Moore and Reynolds, 2016). More specifically, Gilleard and Higgs (2011) talk of how the leaky, less continent bodies of the oldest old are contrasted with the vital performances of younger adults, and Moore and Reynolds (2016) draw attention to a negative aesthetic that equates older people with ugliness and dearth, if not death, of desire. In light of such endemic pathologies and prejudices, it is tempting to believe that older people are generally not only thought of as no longer interested in engaging in sexual activity and pleasure but also are probably not even expected to think of it (Simpson et al, 2018; Bauer et al, 2016). Given the absence of more validating images of ageing sexuality, older people themselves can come to think of themselves in this way (Simpson et al, 2018). It is also quite likely that older people are excluded from the many and varied practices that constitute the ‘sex industry’, though ironically DIY porn sites indicate that older women can be fetishised in a niche way.

Key terms that populate this volume – later life, ageing, ageism, sex, intimacy and ageist erotophobia – were defined in the book series introduction in this volume.
