ATLANTA (CBS Atlanta) — It appears size actually does matter.

A new study finds that women are able to reach orgasm more easily when they are with men that have larger penises, according to LiveScience.

Stuart Brody, psychologist at the University of West Scotland, conducted the study among 323 women by asking them about their past sexual encounters. Of the women polled, 160 of them reached vaginal-only orgasms.

Brody and his colleagues defined the “average” penis size as 5.8 inches to 6.1 inches and asked women if they prefer longer-than-average or shorter-than-average during sexual intercourse.

LiveScience reports that 33.8 percent of women preferred longer-than-average, 60 percent said size didn’t matter and 6.3 percent liked shorter-than-average better. Brody hypothesized that women who had more vaginal orgasms over the past month preferred the larger anatomy.

“Male anxiety about penis size may not reflect internalized, culturally arbitrary masculine stereotypes, but an accurate appreciation that size matters to many women — just as men feel legitimate anxiety when they enter the mating market about their intelligence, personality traits, sense of humor, social status, height, wealth, and other traits known to be favored by women across cultures,” Brody told LiveScience.

The Centers for Disease Control and Prevention consistently promote safe sex for men and women, saying that people should use condoms – which come in a variety of sizes to cater to all sexually active men – and birth control to avoid sexual transmitted diseases and unwanted pregnancies.

The study was published last month in The Journal of Sexual Medicine.
