Squirt.org users are clearly well-acquainted with the immeasurably pleasurable sensations of an orgasm. Users are constantly looking to blow their loads – whether they’re self-servicing or engaging in hot ‘n horny hookups.

But aside from just feeling great, there are also quite a few facts about orgasms that the average Squirt.org user might not know. In honor of National Orgasm Day, here are a few facts about orgasms and sexual climax that might surprise you!

1. Orgasms are better with a partner.

Solo sessions are obviously fun, but you’ll want to double up to receive maximum ecstasy. After an orgasm, your body releases a hormone called prolactin. It basically shuts off your sex drive for up to an hour, which is why you might find yourself suddenly bored with that porn clip you were watching.

However, researches have discovered that men release 400% more prolactin after intercourse compared to a self-induced orgasm, which is why post-sex spooning still feels fantastic.

2. Even guys fake orgasms!

In a recent survey of men, researches found that approximately 28% of guys had faked an orgasm with a partner before. A third of those men said they were too drunk to orgasm, while half of them said their main reason for faking was because they were tired and wanted to go to sleep. Yawn.

3. Multiple orgasms are possible – if you’re lucky.

For most guys, the typical refractory period—the time between your last orgasm and when you’ll be able to get it up again—is anywhere from a few minutes to an hour. However, some rare male body’s produce zero extra prolactin post-orgasm, which allows some lucky guys to achieve multiple orgasms in a single session. Sign us up!

4. Your weight could effect your, uh… output.

The average amount of ejaculate released during orgasm is 3.4 milliliters, which is less than a teaspoon—unless you’re overweight. Men with a body mass index greater than 30 were 69 percent more likely to only produce 2 mL or less of semen during an ejaculation.

5. Orgasms can cure headaches!

Not like you need any convincing, but did you know studies have shown that orgasms can actually cure headaches? An orgasm floods your brain with endorphins—the same feel-good neurotransmitters that are associated with a “runner’s high.” So beat your meat this Orgasm Day – it’s good for your health!

6. Cum is loaded with vitamins and minerals.

Cum is actually only 1 to 5 percent semen. Like many of your bodily fluids, most of the volume is water. In a typical 3.4-mL load, you’ll let out around 10 milligrams (mg) of sodium, 9 mg of fructose—which provides the sperm with energy as they swim—a little less than 2/10ths of a gram of protein, and smaller amounts of zinc, potassium, calcium, and chlorine. Yum!

7. Your semen moves faster than any man can run!

The average speed of your ejaculation is 28 miles per hour, which is almost exactly Usain Bolt’s world-record maximum running pace of 27.79 mph.
