Some people who squirt do so in response to G-spot stimulation. Researchers do not fully understand what causes squirting. The same research found that roughly 29% of participants who squirt report the volume of their ejaculate as approximately 2 ounces. Also, some people may not notice when they squirt.Ī 2013 study found that most people who squirt do so regularly, and many do so weekly or more often. One challenge to research is that it relies on self-reporting, and different people understand squirting to mean different things. The estimated frequency and volume of squirting vary. When this involves the vagina, some refer to it as squirting or female ejaculation, though not everyone with a vagina is female. Expelling fluid is common during ejaculation.
