Hey, cutie. Just wanted to let you know that this story originally ran in our October issue, so if you like what you see, you should probably snag a hard copy ASAP. But after scrolling through hundreds of articles, neither of you can find a definitive answer. Despite millennia of evidence that squirting is a very real thing that happens to some women during sex see the receipts, below , so much about it still remains a big fat question mark.

You just need a urethra. Your urethra is a tube that allows urine to pass out of the body. Ejaculation occurs when fluid — not necessarily urine — is expelled from your urethral opening during sexual arousal or orgasm. Surprisingly so!

On December 24, a group of French scientists published what is probably the first medical-journal article on squirting. They gave pelvic ultrasound scans to seven women who previously reported emitting about a cup full of liquid! By administering the scans after the women peed, and then twice during sexual stimulation, they were able to conclude exactly where the liquid was coming from and what it consisted of—and, spoiler alert, it was pee. There have been plenty of studies done on female ejaculation, this is the first one, as far as I can tell, to specifically explore women who expel great gushing quantities of fluid when sex is happening.

Where does it comes from? Is it pee? And how might I make it happen for me?
