On top of that, the most important confirmation of my research is that men do indeed prefer women without body hair, no matter if it’s located in the leg and/or armpit. In the “choose the most attractive picture” questions, the photo of a woman without body hair was rated significantly more attractive than the one with body hair, with 95.2% of the participants choosing the hairless women. When it came to explaining their answers, the participants stated the following opinions: preferring partners with smooth skin (95.2% of the participants), seeing body hair as an emasculating feature (85.7%), and considering that females “just look better” without body hair (28.5%). These results demonstrate that body hair is associated with femininity, and having a hairless body is an expectation of men towards women.
