I used data from a national probability sample (N > 18,000) of British residents to investigate asexuality, defined as having no sexual attraction to a partner of either sex. Approximately 1% (n = 195) of the sample indicated they were asexual. A number of factors were related to asexuality, including gender (i.e., more women than men), short stature, low education, low socioeconomic status, and poor health. Asexual women also had a later onset of menarche relative to sexual women. The results suggest that a number of pathways, both biological and psychosocial, contribute to the development of asexuality.

The relations between adult attachment processes and sexuality were examined in a community sample of 792 young adults (327 men and 465 women) from the Niagara region of Canada. Participants completed questionnaires that included Simpson's (1990) measure of adult attachment, self-reported physical attractiveness, erotophilia, and a variety of sexual behavior measures (e.g., number of sexual partners, age of first sexual experience, frequency of sexual behaviors in the past year, whether an affair had occurred in the past year, and consistent condom usage). The sexuality measures were factor analyzed to extract common factors. The results were modest, but a number of significant relationships between sexuality and attachment were observed. For example, people scoring higher on a secure attachment index perceived themselves as more physically attractive, whereas people scoring higher on an anxious attachment index perceived themselves as less physically attractive, had an early first intercourse (and more lifetime partners), more infidelity, and took more sexual precautions (e.g., condom usage). The results were generally stronger in women, with most of the attachment/sexuality associations in the full sample being driven by the results in women. Implications for understanding sexual variability, including high-risk sexual behavior, are discussed.

Asexuality has been the subject of recent academic (A. F. Bogaert, 2004) and public (e.g., New Scientist; CNN) discourse. This has raised questions about the conceptualization and definition of asexuality. Here the author reviews some of these issues, discusses asexuality from a sexual orientation point of view (i.e., as a lack of sexual attraction), and reviews the similarities and differences between this definition and related phenomena (e.g., hypoactive sexual desire disorder). Finally, the author concludes that the term asexuality should not necessarily be used to describe a pathological or health-compromised state.

Consensually nonmonogamous relationships are those in which all partners explicitly agree that each partner may have romantic or sexual relationships with others (Conley, Ziegler, Moors, Matsick, & Valentine, 2013 ). In this article, research examining the associations between consensual nonmonogamy, psychological well-being, and relationship quality is reviewed. Specifically, three types of consensual nonmonogamy are examined: swinging, open relationships (including sexually open marriage and gay open relationships), and polyamory. Swinging refers to when a couple practices extradyadic sex with members of another couple; open relationships are relationships in which partners agree that they can have extradyadic sex; and polyamory is the practice of, belief in, or willingness to engage in consensual nonmonogamy, typically in long-term and/or loving relationships. General trends in the research reviewed suggest that consensual nonmonogamists have similar psychological well-being and relationship quality as monogamists. Methodological challenges in research on consensual nonmonogamy and directions for future research are discussed.

The relations between intactness of the parental unit (e.g., father absent at age 14) and pubertal timing in both men and women were examined in a US national probability sample. In both men and women, an absent father at age 14 predicted an earlier age of puberty (e.g., early menarche or voice change). There was little evidence that an absent mother or the presence of a stepfather, independent of a father's absence, was related to early puberty in either men or women. The results extend previous research and suggest that certain psychosocial factors (i.e., father absence) may affect growth and development in both adolescent girls and boys.
