It may seem like men's brains are in their penis, and a lot of what they do is centered on that area. But it seems there's just as much going on in their balls.
"The scrotum isn't exactly the 'prettiest' or most elegant part of the human anatomy; in fact, there are a few in this world that can be quite the opposite. But let's not be too hard on them ... after all, it isn't their fault anymore than we can blame the production of cellulite we find on our backsides, ladies," says Dr. Yvonka, clinical sexologist.
The male scrotum can be used in ways that are enjoyable to males and females, but to what degree may vary, as they're excessively sensitive.
"We can help our SO's achieve a much more pleasurable experience during sexual trysts when incorporating these fun sacks during sexual play, and then later we can use it as a means of punishment when they misbehave," says Dr. Yvonka.
See, everyone wins! All jokes aside, here are a few things to keep in mind when it comes to the family jewels (they're called this for a reason):
1. The origin of the word "testicles" means to "bear witness."
Testicles come from the Latin word Testis, which means to witness. It's believed that in ancient Rome, men had to swear on their testicles in court. We should try that today; there would be a lot less fibbing.
2. Blue balls is a real (and painful!) thing.
Testicles can nearly double in size during sex. All that built-up pressure hurts if not released, and that's where blue balls comes from.
3. They're the male equivalent of ovaries.
The testicles, balls, scrotum, jewels, whatever you choose to call them, are the number one variable in reproduction alongside the ovaries, says Dr. Yvonka.
They're in charge of producing and safe guarding sperm — a common well known fact, but a good reminder nonetheless.
4. They're SUPER sensitive.
Touching, licking, and kissing them can be a powerful burst in pleasure for your man, but no squeezing or biting. OK, maybe a little ... men may enjoy it, but keep it light and only on the skin, not the actual testicle.
"Men get very aroused when you enjoy every part of them down 'there,' as much as women do in the good old-fashioned lumberjack fantasy of 'pick me up and ravish me,'" says Dr. Yvonka.
6. They don't always match in size, just like breasts.
Just as one of our breasts may be bigger or hang differently than the other, the same can be said for his balls.
"It's normal for a male's testicles to hang unevenly. In fact, approximately 85 percent of males have a left testicle that hangs a bit lower than the right. Use this to your advantage by paying enough individual attention to each," says Dr. Yvonka.
7. They can reveal if he's faking an orgasm.
Testicles have a natural tendency to retract when the man is about to orgasm. It enhances sensation when the balls are cupped during climax, although it's also a great indication of true climax, says Dr. Yvonka.
For a few of those male climax fakers out there (yes, they exist), us women can cop a quick feel during your "orgasm" if we're suspicious.
8. Coldness is their enemy.
Testicles also shrink when they're cold because it's the body's natural way to protect itself, just as they hang down and are loose when you're too warm in an effort to release heat.
"The temperature for sperm production has to be 'just right,' which makes the scrotum an excellent natural heating and cooling machine. Unfortunately, it's just for that one specific area," says Dr. Yvonka.
Looks like there's serious truth to that Seinfeld scene afterall.
9. Most important of all, they should be handled with care.
Squeezing too hard could release a vast amount of adrenaline into the body that could be deadly, along with the instinctive reaction of whomever those balls belong to. So always be gentle!
