The present study explored the marital and sexual satisfaction of a sample of 1,376 men and women swingers via an on-line survey. Marital and sexual satisfaction scales were used to measure the levels of satisfaction of the sample in both variables. Demographics characteristics of the sample, attitudes towards swinging experiences, and swinging sexual behaviors were also examined. Data analysis revealed that both men and women in the sample scored at the high end of the marital and sexual satisfaction scales. Further statistical procedures yielded minimal differences between the scores of men and women in those measures. The swinging experience was measure by multiple choice questions. Regarding swinging activities and experiences, men and women swingers reported being satisfied with their swinging activities. Men were more likely than women to have suggested swinging to their partners; the two major reasons given for engaging in swinging activities were sexual variety and fantasy fulfillment; most of the participants reported participating in swinging activities four to five times a year and finding their swinging partners via the Internet. The demographic data revealed that the individuals in the sample were mostly white, aged between thirty and fifty years of age, in their first marriage, college educated from urban or suburban areas, and with a mean income between forty and seventy five thousand dollars yearly. Most of the men reported being heterosexual while a small number reported being bisexual; over half of the women reported having a bisexual orientation and only a small number were heterosexual. The limitations of the study were described and discussed and the following recommendations were suggested. Further research is needed with the swinging population to determined the impact of swinging on the family unit, engage in further research with couples to evaluate the responses of each individual, and conduct a comprehensive longitudinal study to gather information on the long-term effects of swinging on the marital relationship.
