The orgasm gap, the phenomenon in which men have more frequent and regular orgasms during partnered sex than women, has been well documented in the research.

Many factors influence orgasm. Biological, psychosocial, and interpersonal factors are known to play a role—for instance, couples with poor sexual communication are less likely to experience reliable orgasms. In general, people are more likely to reach orgasm with established partners than during casual sex encounters.

Previous studies have explored the link between orgasm frequency and gender as well as sexual orientation. Across the board, men have orgasms more reliably than women. This is likely because an orgasm typically accompanies ejaculation, which is needed for procreation.

Furthermore, gender socialization and culture have placed more emphasis on male sexual pleasure compared to women’s. While there is some valid debate, many argue that aside from pleasure, there is no evolutionary need for the female orgasm, which is why orgasms can be more challenging for women. As it relates to sexual orientation, research has shown that heterosexual men have the most orgasms, followed by gay men, bisexual men, lesbian women, bisexual women, and heterosexual women.

Little is known, however, about how orgasm frequency correlates with race and ethnicity. A new and interesting study sheds some light. Race-based sexual stereotypes are shaped by culture and systemic power differences. This type of sexual racism influences people’s beliefs........
