Both academic and lay definitions of sex vary. However, definitions generally gravitate around reproduction and the experience of pleasure. Some theoretical approaches, such as psychoanalysis and evolutionary psychology, have positioned sexuality at the center of psychological phenomena. Much research has also linked sex to health and disease. On the one hand, certain sexual thoughts, feelings, behaviors, and identities have been described as pathological. Over time, some of these have been accepted as normal (especially homosexuality), while new forms of pathology have also been proposed (e.g., “porn addiction”). On the other hand, some aspects of sexuality are being researched due to their relevance to public health (e.g., sex education) or to counseling (e.g., assisted reproduction). Sex research has always been controversial, paradoxically receiving both positive attention and disdain. These contradictory social forces have arguably affected both the content and the scientific quality of sex research.

Since the first cluster of people with HIV was identified in 1981, significant biomedical advances, most notably the development of antiretroviral therapy (ART), have led to considerably increased life expectancy as well as a reduction in the morbidity and mortality associated with HIV/AIDS. As a result, HIV/AIDS is no longer considered a terminal illness, but rather a chronic illness, and many persons living with HIV/AIDS are beginning to enter or have already reached later life. In fact, Americans ages 50 years and older comprise approximately half of all individuals with HIV/AIDS and represent the most rapidly growing subpopulation of persons living with HIV/AIDS in the United States. Despite significant advances in HIV/AIDS treatment and prognosis, older adults living with HIV (OALH) face a number of unique challenges and circumstances that can lead to exacerbated symptoms and poorer outcomes, despite demonstrating generally better ART adherence than their younger counterparts. These detrimental outcomes are due to both chronological aging and cohort effects as well as social and behavioral factors and long-term ART use. For instance, neurocognitive deficits and neuropsychiatric symptoms, including depression, anxiety, apathy, and fatigue, are often observed among OALH, which can result in feelings of loneliness, social isolation, and reduced social support. Taken together, these factors can lead to elevated levels of problems with everyday functioning (e.g., activities of daily living) among OALH. In addition, sociocultural factors such as race/ethnicity, ageism, sexism, homophobia, transphobia, geographic region, socioeconomic status and financial well-being, systemic barriers and disparities, and cultural values and beliefs play an influential role in determining outcomes. Notwithstanding the challenges associated with living with HIV/AIDS in later life, many persons living with HIV/AIDS are aging successfully. HIV/AIDS survivor and community mobilization efforts, as well as integrated care models, have resulted in some significant improvements in overall HIV/AIDS patient care. In addition, interventions aimed at improving successful aging outcomes among OALH are being developed in an attempt to effectively reduce the psychological and physical morbidity associated with HIV disease.
