What actually happens
Squirting refers to fluid released from the Skene's glands (sometimes called the female prostate) during arousal or orgasm, typically with G-spot stimulation involved. It's a genuine physical response for people who experience it, not something performed or faked, though how much fluid and how reliably it happens varies enormously from person to person and even session to session for the same person.
Is it the same as urine?
This is the most common question, and the honest answer is: mostly no, but it's genuinely complicated. Research on the fluid's composition has generally found it's chemically distinct from urine and closer to prostatic fluid, though studies have also found it can contain a small amount of urine in some cases, particularly with larger volumes. If the "is it pee" question itself is what's holding you back mentally, using the bathroom beforehand addresses the practical concern directly regardless of where you land on the underlying science.
Can everyone do it?
No, and that's not a problem to solve. Some people experience it consistently, some occasionally, and some never, regardless of arousal level, technique, or how good the sex otherwise is. It isn't a marker of a "better" or more intense orgasm, and treating it as a goal to hit tends to create pressure that makes it less likely, not more — the same paradox that shows up with a lot of sexual response.
Technique that actually helps
G-spot stimulation — a "come hither" motion with fingers or a curved toy against the front vaginal wall, a couple inches in — is the most consistently reported trigger, especially combined with simultaneous clitoral stimulation rather than G-spot stimulation alone. Staying relaxed matters more than most technique advice suggests: tensing up in anticipation, or feeling self-conscious about mess, tends to work against it. A towel down in advance removes that specific worry and is a genuinely practical first step, not just a comfort measure.
