A study from the University of Mexico and UCLA has determined what exactly a woman is looking for in her “perfect penis.”

The researchers wanted to figure out what women were actually hoping for when a man pulls down his pants, and in order to do it they actually used 3D-printed penises so that women could judge every part of it, including girth.

The study is unlike other previous attempts to pin down a woman’s preferred penis size since the previous tests included just asking questions about favorite size or taking a look at paper drawings. The newest researchers wanted to give a better idea to the women that they were surveying, however, and went with the eye-popping 3D penises to help narrow the field.  

And the results of the study? Well, guys, you can stop holding your breath if your erections are just on the average side.

Per the study, "A and D represent the largest and smallest models in the set, respectively; B and C represent the two models (counterbalanced) used to test recall for size."

It turns out that women really weren’t into the Ron Jeremy types of the world. Yes, that’s right: Women don’t want giant penises. And the type of penis we’re searching for actually depends on what we’re planning on doing with it, interestingly enough.

The researchers asked 75 women to judge 100 different erect penises and then narrowed those down to 33. Of the remaining 33 (which were then 3D-printed), they asked the women to put the penises into two different categories: dependable, long-term relationship material, or sultry one-night stands.

For the heated one-night stands, the women in the group preferred a penis that was slightly bigger than average — somewhere around 6.4 inches long and about 5 inches around. But for the long-term relationships, they didn’t even want their penises to be that long.

The relationship-favored, dependable penis only needed to be about 6.3 inches long with a circumference of 4.8 inches. This is nowhere near the forearm-length penises that most pornos would make you believe that women want.

Of course, there’s a lot more to take into consideration than just the penis, since there’s a whole person attached to said penis, but fellas, you can breathe a sigh of relief. It turns out, science just proved that it really is the motion of the ocean and not the size of the boat.
