We Now Know Women Prefer This Penis Size, Thanks to 3-D Printers

What happens when a study about penis size preferences and 3-D printers collide? Weird science, that's what. Scientists used a 3-D printer to create 33 penis-like figures of varying length and girth (see them here, and print one for yourself if you're so inclined!) because, "Studies of women's penis size preferences typically have relied on their abstract ratings or selecting amongst 2-D, flaccid images," says the study. Well OK then.

The study, published yesterday in science journal PLOS ONE, aimed to assess if the context of the relationship (say, one night stand vs. long-term potential) affected women's preference in size.

The verdict? Apparently women have larger standards for a one-night stand than they do for a long-term lover. According to the study, "Women preferred a penis of slightly larger circumference and length for one-time (length = 6.4 inches/16.3 cm, circumference = 5.0 inches/12.7 cm) versus long-term (length = 6.3 inches/16.0 cm, circumference = 4.8 inches/12.2 cm) sexual partners."

Averaging out both categories, it looks like a penis length of 6.35 inches and circumference of 4.9 inches might be ideal for any type of relationship, at least based on this data. If that's the case, it looks like the average penis in the U.S. is falling 1/3 of an inch short for most women: "Based on previous studies...the average American erect penis length was estimated as 6 inches (15.2 cm) and circumference as 5 inches (12.7 cm)," the study explains.

The study included 60 women ranging in age from 18 to 65, all California residents. Twenty-seven percent of them had ended a relationship due at least in part to unsatisfactory penis size (for the record, more cited that the issue was a too-small penis, not a too-large one). If you find yourself on the verge of the same decision, maybe give these sex tips a try first to see if you can make up for the lack of size in other ways.
