Comparative sexuality of conspecific stream-side and stream-rock mosses

The sexuality of conspecific stream-rock and stream-side bryophytes at Cement Creek in the Yarra Ranges National Park, Victoria, Australia was examined in terms of sex ratios and sporophyte production. Generally, stream-side colonies had higher numbers of stems, inflorescences and gametangia than their stream-rock counterparts. A higher number of stream-side than stream-rock species produced sporophytes although Cyathophorum bulbosum (Hedw.) Mull.Hai. produced more sporophytes on stream-rocks than in the stream-side habitat. Sex ratios generally showed a female bias with regard to stem numbers and number of inflorescences.

Relationships, sexuality and adjustment among people with physical disability.

The current study investigated the association between relationship status and the psychological adjustment, sexual esteem and sexual behaviour of people with and without physical disability. A total of 1196 participants completed the study, 748 participants (367 men, 381 women) had a physical disability and 448 participants (171 men, 277 women) were able-bodied. The age range of participants was 18 to 69 years, with a mean age of 36.39 years (SD=10.41). The results demonstrated that physical disability and its severity were related to an increased likelihood of being single. Men with physical disabilities were more likely than women to be single. In terms of psychological adjustment, single people with physical disabilities were more depressed than those who had a partner they did not live with. However, they were not significantly disadvantaged in this area when compared to married people and those in de facto relationships. Relationship status was strongly related to sexual wellbeing in people with and without physical disability, with single people reporting lower levels of sexual satisfaction and sexual esteem as well as less frequent mutual sexual activity. However, married people with physical disabilities reported lower levels of sexual wellbeing than the people who had partners they did not live with. This suggests that among couples where a partner has a physical disability, marriage and live-in relationships may add burdens that do not exist in more casual relationships.

Exacerbation of symptoms among people with multiple sclerosis: impact on sexuality and relationships over time

This study was designed to evaluate the impact of an exacerbation in symptoms among men and women with multiple sclerosis (MS) on sexuality and relationship satisfaction. A total of 321 people with MS (120 men, M age = 48.10 years; 201 women, M age = 45.78 years), and 239 people from the general population (79 men, M age = 53.93 years; 160 women, M age = 45.89 years) completed measures of relationship satisfaction and sexuality, and then completed these measures again 18 months later. The results demonstrated that both men and women with MS reported significantly higher levels of sexual dysfunction than did the general population. The no exacerbation group also reported significantly lower levels of sexual activity and of relationship satisfaction than the general population group over the 18-month period. Women in all groups reported significantly higher levels of sexual dysfunction but also higher levels of sexual activity than did men at each time period. They also reported significantly higher levels of sexual satisfaction at the 18-month follow up. These results suggest that men and women respond in similar ways to MS, and that people with MS do not necessarily experience poorer levels of sexual interaction or relationship quality when they experience an increase in their physical symptoms.

High-functioning autism and sexuality: a parental perspective

Few studies have compared sexual behaviours among adolescents with high-functioning autism (HFA) and typical populations, and indicated whether specialized education is required. We hypothesized that adolescents with HFA would (1) display poorer social behaviours; (2) engage in fewer behaviours related to privacy and have poorer knowledge regarding privacy issues; (3) have less sex education; and (4) display more inappropriate sexual behaviours; and that (5) parental concerns would be greater for the HFA sample. Parents of typical adolescents (n = 50) and adolescents with HFA (n = 23) were surveyed with a Sexual Behaviour Scale (SBS) developed by the authors, with domains corresponding to the hypotheses. The HFA and typical groups were found to be significantly different on all five domains. However, following covariation with age and level of social behaviour, it was found that only parental concerns about their child distinguished between typical adolescents and those with HFA. Specialized sex education programmes with a social interaction emphasis should be considered for this group.

On the borders of sexuality research: young people who have sex with both males and females

As D' Augelli and Grossman point out, there is an underrepresentation in LGB research of "youth who have had sexual experiences with both males and females." Indeed, Heath (2005) refers to the "silent B" in much GLBT research. And, Owens (1998, p. 55) discusses how heterosexism "formalizes a societal dichotomy of heterosexuality versus homosexuality with little room for bisexuals" in educational research. Most of the information on bisexuality has been obtained from studies with adult samples, and it is "unclear to what extent a separate bisexual cultural identity is consolidated during adolescence" (Ryan & Rivers, 2003, p.105). As Bryan, a 17-year-old bisexual young man in my research, declared: "It's simple bullshit logic! They don't have evidence of bi kids in schools because they don't want to find it and so don't write their research looking for it."
