Squirting in porn has become nothing short of a phenomenon. According to Pornhub, the world’s most popular porn-streaming site, interest in the act–also known as “shejaculation” or “gushing”–is at an all-time high after first gaining momentum in 2013. Today, squirting is one of the website’s most popular video categories—but more interesting is that women are more likely than men to search for videos of the act.

Of note, Pornhub found women are almost 50 percent more likely to search squirting-related content online than men. These interests are most popular among adults ages 18 to 34 and geographically, in Wyoming, Montana, Utah and Nebraska. Surprisingly, Pornhub squirting searches are lowest in California, porn’s capital, as well as New Jersey, Maryland and New York were lowest. But why? What’s so appealing about a sexual sprinkler?

According to Bree Mills, an award-winning adult-entertainment writer, director and producer, squirting is not only impressive to witness but it can be a marker of how good you are at lovemaking. “When you have sex with women, squirting is up there on the list of Holy Grail achievements with the g-spot orgasm,” Mills tells Playboy. “It doesn’t happen that often in real life, but if you can make a woman feel so good that she ejaculates, it’s quite an accomplishment.”

The legitimacy of squirting has long been speculated by sex and medical professionals alike. Earlier this year, Playboy’s resident sex educator and researcher Justin Lehmiller, recently wrote on the subject reported on the latest research on the act. According to the latest studies, female ejaculate comes in two forms. The first and most common is a small amount of white, milky fluid released through the urethra. The fluid closely resembles male ejaculate, both chemically and in apperance. The source of this fluid is the Skene’s glands, tiny structures beneath the bladder that surround the urethra and consist of prostate-like tissue.

The other type of ejaculate is what’s produced when a woman squirts. In this case, the liquid is more watery and originates in the bladder. The liquid primarily comprises urine with trace amounts of prostate-specific antigen (PSA). This suggests that, during squirting, there may be a small contribution from the Skene’s glands in some women. This also means the fluid is mostly pee. So there’s that.

“Repeat after me, squirt is not real—it is piss,” adult star Eva Lovia tells me. “If a girl just had vitamins, [the fluid] will be bright yellow. If she does not chug a gallon of water before the scene, she can’t squirt. Basically, women who can release all that fluid during sex are just releasing their bladder. Does that make it less appealing? I hope so.”

A study from earlier this year revealed only 18 percent of female porn stars achieve real orgasms on film compared to almost 80 percent of men. If that’s the case, and the majority of female porn stars aren’t experiencing authentic orgasms, is squirting then just a crutch utilized by porn-makers to make their scenes more impressive—and primal—while simultaneously making women who can’t perform the act feel inadequate?

Mills reveals that a lot of the squirting scenes you watch are fake. “I think the increase in squirting porn has led to some performers and producers finding ways to fake it in order to meet the demand. Ultimately, it comes down to knowing which actresses are real squirters versus those who are not.” Still, Mills argues that the sex act is achievable. “Being able to make a girl squirt during penetration is definitely a real thing,“ she argues. "The ones who can do it for real are easy to identify because they are almost always doing it in [every] scene these days.”

Like many fantastic sex fables, each bit of added information seems to contradict the previous. What we know for sure is that squirting—as in, the very act of the word—is real. Yes, women can release fluid from their genetalia. But squirting as a testament to a man or a woman’s lovemaking is not proven. Something else we know is that the percentages of women who can versus those who cannot have not been verified. For that reason, whether a woman can doesn’t matter. Or it shouldn’t matter.

Like men who want bigger penises, porn’s unrealistic standards can make women feel inadequate in their lovemaking. So let’s look at squirting for what it is: an impressive sexual act that some women can achieve. Should it be celebrated? Sure; according to Pornhub, many of us love it. But should we embrace the sex act so much as to accidentally condemn those who cannot perform it? Absolutely not. Given that male anatomy rarely measures up to the unrealistic standards of porn, at least half of us are in no position to make demands.
