Published in the Journal of Sex in October, the researchers asked women about the last date of sexual intercourse as well as who had the final say on decisions ranging from healthcare to household purchases.
According to the Telegraph, the researchers surveyed women from six African countries who reported the more decisions made, the less physical intimacy they shared with their partners.
“The more decisions a woman reported making on her own, as compared to through joint decision-making, the less likely she was to have sex and the longer it was since she last had sexual intercourse,” said lead researcher Michelle Hindin.
The findings showed more dominant and assertive women had approximately 100 times less sex.
But the researchers also noted that this isn’t necessarily incidental for them — it could also be women taking control of their sexual preferences, the Daily Mail reported.
“Understanding how women’s position in the household influences their sexual activity may be an essential piece in protecting the sexual rights of women and helping them to achieve a sexual life that is both safe and pleasurable,” co-author Carie Muntifering told Health24.com.
The location of the women studied may also have played a role, though. Most recently, a study by Florida State University’s Roy Baumeister argued that more equality would lead to more sex. He pointed to a study surveying over 300,000 people from 37 countries which found that countries with a higher gender equality had more casual sex and more sexual partners. In nations with less equality between the sexes, the opposite was true.
