Anatomy of the penis. Let’s talk about it. We’ve all got one, but there’s some things we may not know. We’ll cover basic anatomy, what the parts do, and what makes us feel good. We will also talk about when things go wrong, and some basic facts that sometimes get overlooked about our Johnson’s. The goal of this post is to educate about what we have, what feels good, and why it feels good.

Anatomy Overview

The picture above shows the basic anatomy of the male reproductive system. We’ll get into more detail below about the anatomy of the penis. As you can see, there are several parts inside and outside the body cavity. The scrotum protects and regulates the temperature of the testes. This fascinates women when your balls just move around on their own. This is also why they shrink when they are cold and hang lower when it’s hot. It should also be noted that there are men that are “grow-ers” and “show-ers”. Grow-ers are small flaccid, and grow sometimes multiple times their flaccid size. Show-ers are roughly the same size flaccid or erect, the only difference is hardness.

As you can see, there’s a few reproductive parts inside. We tend to think of just the penis and the scrotum/testes as our reproductive parts. But there’s more to it than that, and more ways to please us than just our penis.

The vas deferens carries the sperm from the testes (5% of the ejaculate volume) to the urethra and the seminal vesicles. As the sperm passes through the seminal vesicles in the vas deferens, the seminal vesicles add the seminal fluid (50-65% of the ejaculate volume) to the ejaculate. Then the prostate adds some more fluid (roughly 20-30% of the ejaculate volume). When you ejaculate, the prostate squeezes and closes off the bladder from the urethra, pushing the ejaculate out of the body. Because the prostate closes off the bladder, it’s not possible to pee and ejaculate at the same time. You can read more about this at Medical News Today.

Shaft Anatomy

Erections are the result of blood being pumped into the penis. the “top” of the shaft is made up of a structured spongy material called the Corpus Cavernosum. This spongy material fills with blood and makes your dick erect. When it fills with blood, there is a membrane that traps the blood inside the penis. Along the bottom, where the urethra is, there’s a different kind of erectile tissue that isn’t as firm so the urethra can pump out ejeculate.

Now that we’ve covered some of the basic anatomy of the penis and sex organs, we should use this time to cover some more medical information. When you get a vasectomy, the doctor cuts and ties off the vas deferens inside the scrotum. They make a small incision on each side of the scrotum, pul out the vas deferens. Then it is cut and knotted off, and in my case cauterized. If you are considering getting this done, my experience was stellar. The anticipation leading to the event was worse than the event itself. Doctor’s require you to have 24 “emissions” to clear out the pipes before you come back for the verification test. This is what I called “the fun part”.

Erectile Dysfunction

Something that no one wants to talk about is ED, Erectile Dysfunction. When our little soldiers can’t perform, it’s time to talk to a doctor. There are some things we can pay attention to before we talk to the doctor about the issue. For example, notice if you have trouble with morning wood or not. Notice if you have difficulty getting hard at different times of the day. Pay attention to non-sexual things, like stress, eating habits, emotional state, and exercise habits. Any changes in these things can be clues as to what is causing our problems. There will be a longer post about ED at a later date. Keep and eye out for that!

Now we need to talk about pleasure. Just like the post about women’s anatomy, discussing what feels good and what doesn’t in the context of the anatomy of the penis is one of the main goals of this blog.

We’ll start at the tip and work our way down because 90% of the nerves in our penis are in the first 1-2 inches. The head, or glans, should get a lot of attention from your significant other. Experience has taught me that the frenulum is the magic spot. There’s a concentration of nerves there, on the bottom of the shaft right were the glans connects to the shaft. The shaft and the balls feel good too, but the glans and the area right below the head are the highest concentration of nerves. If it’s a hand job or a blow job, asking her to concentrate on these areas will feel great. But that doesn’t mean your SO should ignore the balls and the shaft. It all feels good, so don’t be afraid to communicate with her (discussed here)!

Prostate and Butt Stuff

Butt stuff. Some people don’t enjoy this, and that is OK. However, there are a lot of pleasure nerves inside your ass. Including the prostate. If you doubt me, look up “prostate milking” on your favorite porn website. If you expect your lady to let you play with her ass, you should think about letting her play with yours. You can experience a lot of pleasure from “butt stuff”. Don’t be afraid of it because of social stigma. Who cares what you do in your bedroom, let your freak flag fly high!
