So that’s who your dick is now what does he do? Penises have three main functions: urination, sexual gratification, and reproduction. Let’s start with taking a piss. We all do it and we all know how to do it but let me tell you how your body does it. The process begins with the deliberate signal you send to your brain letting it know that you’ve got to take a leak. A similar signal is sent to your brain to incite the release of urine, but not before the pathway from your testicles is involuntarily closed and your urethral sphincter muscles relaxed. Then, ahhh, urination. The sphincter muscles are used to control the flow of urine from your urethra and are much stronger in men than they are in women. Not only does that mean that we win the high-stakes bet of who can hold the most pee for the longest, but where a woman empties her bladder with the help of gravity, men can actually expel urine by contracting a specific muscle.
In addition to helping keep your system litter free, your penis has the far more glamorous job of administering pleasure. One of the ways it does that is by becoming erect. This process starts with a series of complex neurochemical steps, beginning with psychological interest, erogenous zone stimulation (whether it be the penis or beyond), or direct fluid manipulation (penis pump or the wag technique, which I’ll tell you about soon enough). From there the blood flow to the penis increases due to favorable pressure gradients (blood in, blood out) and arterial dilation. The result from this is that the symmetrical spongy tissue becomes progressively filled and the pressure inside these areas increases until a steady state is reached. Voila, erection. Because the intravascular pressure is greater in the penis than where the blood is originating from, the erection is maintained. However, once that changes and the amount of blood and pressure in the penis dissipates the erection is lost.
Each of these three responsibilities is supported by at least one other element of male genitalia. And although we’re limiting our discussion to the boundaries of pleasure, many of the same parts that help you reach climax also serve to run your system effectively. Take your testicles for example. Located outside of the body to provide a cooler climate for sperm growth, the testicles are equal parts reproductive tool and sexual mechanism. Remember, sex isn’t just about sticking your penis into a woman’s vagina and your balls should be a good reminder of that.
Testicles, also called gonads or testes, are the male sex glands and produce sperm and hormones for their bearer. Egg-shaped and tough as nails, these guys are an industry unto themselves. In addition to producing sperm they also create testosterone and are part of the body’s endocrine system, an intricate hormonal routine that keeps your machine going. Testicles are packed with nerve endings and if you’ve ever been hit in the nuts by a wayward ball or angry ex-girlfriend’s knee, you can attest to this fact. So why does it feel so good when your current girlfriend rubs, tugs, and squeezes the life out of them? Who knows. Just be thankful it’s not a knee.
Most men have two testicles and in every man, there is a slight difference between the size and hang time of his balls. One may hang low while the other wobbles to and fro. Both, however, are housed in the scrotum, a dual-chambered sac made out of skin and muscle and separated by a fleshy divider called the septum. The scrotum, too, is loaded with nerves and blood vessels and in addition to keeping sperm cool when away from the body, it can also contract towards the body for warmth or protection. But you needn’t wait for poor weather to get your balls jumping, fellas. Clench your anus and pelvic muscles with the help of Kegel exercises and you can lift your balls any time of the year!
During intercourse you may have experienced your testicles moving, seemingly on their own. And if you haven’t figured it out already, let me be the one to tell you that that’s a good thing. One study found that at least partial elevation of the testicles was needed to achieve full ejaculation. This finding highlights the importance of testicular movement in regards to your orgasm. Let me put it this way, why settle for a top round steak when you can have the rib eye? Why settle for a decent orgasm when you can have a bed-breaking one? For most guys, your penis will naturally raise and hug the shaft of your dick right before you come. Nevertheless, when you include your balls and scrotum in sexual play, you are not only increasing your potential for a full erection and ejaculation, but you are also broadening your range of pleasure.
