Sexual Variety in Norwegian Men and Women of Different Sexual Orientations and Ages.

The purpose of this study was to examine Norwegians' reports of seven varied sexual acts. Data were obtained from a questionnaire survey of a probability-based web sample of 2,181 men and 1,967 women aged 18-89 years. Among seven acts of sexual variety, the most common sexual experiences were trying to watch pornography with a partner, engaging in sex in unusual places, and using sex toys. Older age was negatively associated with all sexual behaviors. Regarding more unorthodox acts of sexual variety, heterosexual men's sexual preferences involved having and desiring group sex, whereas heterosexual women's sexual experiences and desires involved having sex in unusual places. Lesbian, gay, bisexual (LGB) individuals generally showed greater curiosity or experience of having group sex and engaging in BDSM (bondage, discipline, dominance and submission, and sadomasochism) activities than heterosexual adults. However, while LGB men had a high preference for group sex activities, LGB women had more positive attitudes toward BDSM activity. Individuals appear to accumulate more acts of sexual variety over time, thus making the incorporation of sexual variety a function of age. This study supports the idea that sexual variety has expanded among those born from 1960 onwards.
