Sex and handedness differences in the use of autoerotic fantasy and imagery: A proposed explanation

Abstract

Previous research has described a greater use of fantasy and imagery during masturbation by men, than women. This study suggests that this gender disparity results from the increased frequency of bilateral speech representation found in the female brain. Support for this theory was obtained by comparing the use of autoerotic fantasy and imagery in another group distinguished by their degree of cerebral lateralization: dextral vs. sinistral males. The prediction that masturbatory fantasy and imagery would be more common in the more lateralized dextral males was partially confirmed in this study.
