It seems cliche, but it just might be true. The more sexist a man is, the more likely he is to be into big boobs.
A recent study from the University of Westminster, published in February in the Archives of Sexual Behavior, showed that men’s attitudes toward women influence their attitudes about ideal breast size. The researchers interviewed 361 white, heterosexual men, ranging in age from 18 to 68. (Since ethnicity has been previously shown to impact how individuals perceive breast size, the researchers decided to pull participants from just one self-identified racial category.) Each man was shown five different 3-D models of women, each with a different breast size, and then asked to record which “woman” he found most physically attractive.
Afterward, the participants were given surveys which measured each man’s level of hostility toward women, his attitudes about relationships between men and women, benevolent sexism and how much he objectified women.
