Researchers from Swansea University conducted a survey showing that a third of men and 11% of women in the UK would like to have more than one steady partner. The Daily Mail reports. The authors of the work asked 393 heterosexual men and women about their attitude towards open relationships in which they would have to share a partner with other people or have several partners themselves. A third of men and 11% of women said they were willing to have more than one partner. At the same time, 5% of women and 9% of men were willing to give a partner freedom. People were much less interested in multi-person marriages, which involve mutual consent and a formal marriage. Respondents were also asked about polygamous marriages, when a man marries more than one woman, and polyandry, when a woman marries more than one man. Men were 3.5 times more likely to say yes to polygamy than to polyandry. Women were twice as likely to agree to polyandry as to polygamy.
