Every person’s body is different, but there are a few physical signs of an orgasm. The most noticeable sign is a very intense, pleasurable feeling in your genitals and throughout your body. The muscles in your vagina or penis, as well as your anus, contract (squeeze) about once per second, 5-8 times. Your heart rate and breathing levels also go up.
During an orgasm, your penis usually squirts a small amount (1-2 tablespoons) of semen (cum) — this is called ejaculation. It’s possible to have an orgasm without ejaculating or to ejaculate without having an orgasm, but they usually happen together.
It’s common for your vagina to get really wet before and during an orgasm. It’s also possible for a different fluid to squirt or dribble out of your vulva before or during an orgasm (this is sometimes called female ejaculation, or squirting). This fluid isn’t pee. Ejaculation from a vulva is less common than ejaculation from a penis — some people do it and some people don’t — either is totally normal.
Right after an orgasm, your clitoris or the glans (head) of your penis can feel very sensitive or uncomfortable to touch. You may have a “sex flush” — your chest, neck, and face change color for a short amount of time. Orgasms release endorphins (feel-good hormones), so you might feel sleepy, relaxed, and happy afterward — this is why some people orgasm to relieve pain, and stress, or to help them go to sleep.
Orgasms don’t feel the same for every person, or every time you have one — some are very intense, some are very mild, and some are in-between. They vary for a number of reasons, including how comfortable you are, how sexually excited you are, and how much sexual tension you built up before you had your orgasm.
