    For much of man’s existence the orgasm—both male and female—was a total mystery. While we still don’t have an all-encompassing understanding of the O zone, we know a heck of a lot more thanks to the research of brave pioneers like Alfred Kinsey and William H. Masters. Read on and be blown away by our 10 facts about blowing your wad. 

    1. Full Speed Ahead

    When a guy’s about to get his rocks off semen travels through his urethra at a swift 28 miles per hour. Once inside a woman’s fun tunnel, however, ejaculate comes to a crawl, moving at a sluggish .0011 miles per hour. That’s some serious deceleration.

    2. Ladies Go Longer

    A female’s orgasm can last anywhere from 13 to 51 seconds, while men tap out at 10 to 30 seconds. However, as you’ve probably discovered, men reach orgasm more quickly and more often. Do your gal a favor and slow down; she’ll need 8-15 more minutes of sex than you to reach her happy place.

    3. No Touching Required

    Some women don’t even require physical stimulation to reach orgasm. Studies have shown that some gals can get off through thought alone. While no man has proven he can accomplish that feat, members of both sexes have reported hitting the O zone through non-genital touching.

    4. Out of Control

    In both men and women, the brain region behind the left eye, called the lateral orbitofrontal cortex, turns totally off during climax. This area is the seat of reason and control, which is why during an orgasm you lose jurisdiction over your own body and mind.

    5. This is Your Brain On Drugs

    Using either PET or CAT scans, researchers can evaluate which areas of the brain light up during an orgasm. As it turns out, in the throes of passion our brains look almost exactly the same as the brain of someone injecting heroin. So, getting off is a much safer way of getting high.

    6. No Need for Aspirin

    Since the body releases feel-good hormones dopamine and oxytocin during orgasms, a session between the bed sheets can actually alleviate pain associated with headaches, arthritis and injuries. Moreover, studies show that even just thinking about sex may provide a little relief. So go ahead and fantasize, it’s good for your health.

    7. She’s Got Nerve

    Most women can’t climax through vaginal intercourse alone but require a little clitoral stimulation as well. Perhaps this is because that little love button has a whopping 8,000 nerve endings, which is double that of the average penis. Now there’s a small spot that packs a big punch.

    8. All Over Your Body

    Both men and women have reported feeling orgasms in non-genital places on their bodies, like their hands and feet. Even odder, amputees have described orgasms in limbs that no longer exist (scientist think this is caused by a remapping of the brain after losing the body part).

    9. Semen Stats

    Each time a dude busts a nut, he releases between 40 and 600 million sperm depending on the volume of baby juice and length of time since he last got off. Over a lifetime, the average man ejaculates at least 14 gallons of sperm.

    10. The Learning Curve

    A study done at Indiana University found that while 85 percent of men say their female partner had an orgasm during their last sexual encounter, only 65 percent of women concur. However, when looking at couples in long-term relationships, that ladies percentage jumps up to nearly 80%.
