The urethra appearing smaller in the erect diagram compared to the flaccid diagram actually explains a lot on how it feels harder to urinate when you are erect.

Yep. That mushroom footage… 🍄⬆️🤣
I suppose it depends on where in the world your from, some countries have funny attitudes towards sex *cough USA* lol. But I think most don't find a perfectly normal & natural function of the human body "taboo" or embarrassing...
@@jmiller991 exactly. Ignorance breeds ignorance.
@@jmiller991 In US, pop culture (i.e. Hollywood mainstream cinema, pornography,) mainstream media/journalists, special interest groups (of all sides) and the non-medically trained politicians who get their talking points are the factors that determine the cartoonish current maninfestations on sexual topics.
What results is a politically correct, WOKE mutant mess, seasoned with the puritanical history of country. Real science (some established for last 2,500 years and reconfirmed numerous times in between) be damned what's presented is to assure presenter a guest shot on Jimmy Kimmel or the 700 Club, resulting to just please noisy fanatics, deviant billionaires that feed politicians' coffers, and those who what to have pre-existing errata validated..
@@jmiller991 Exactly. For example, here in Sweden, we talk about sex all the time. With our friends, our families, our children, and even strangers. I'm glad we are a sex open country where sex is not ashamed or embarrassing, but instead encouraged in teenagers and young adults. Sex education is always important and everybody should learn about how our bodies work!!
As a guy this is both painful to watch yet informative.

At 50 years old I’ve learned more from your channel than I did as a high school graduate. I wasn’t able to go further due to the death of my father 1985 less than a month of turning 14 from that point on I cared for my paraplegic mother until April 24,2018 when she passed. That by far was a much more rewarding experience than any college could have provided. The amount of medical knowledge I now have,one would think I went to medical school 😁thank you for amazing videos as I love to learn. You know what they say…you never stop learning and your never too old to keep learning. Blessings 🙏❤️
Here’s one you will like then Ms. Patty. Your and you’re are not interchangeable. You’re is a contraction of the phrase you are, while your is a possessive adjective used to show ownership. It is not a contraction.

Has anybody ever studied whether having a curve/asymmetry is an evolutionary adaptation/variation? It would be interesting to see a population study that graphed erection curves on a bell curve (2 degrees, 10 degrees etc.).
I believe so. Also, HI TAYZONDAY OMGG
lmao Tay Zonday whats up
Fun "only verified by me" Fact: TMI perhaps but I was rather promiscuous in my youth so... 😇
I've noticed that red haired men (Irish more than Scottish) tend to curve to the left or the right, sometimes at extreme angles (up to 15-20%).
I have also discovered that Identical Twins (Mirror) will have curves (or direction? One points up, the other down) in both directions. Something I found both fascinating and funny (in a good way).

Maybe you did on ahem *other sites*. You should know that your phone is spying on everything you do so it doesn’t have to be recommended based on TH-cam searches

You mean your recommendations? This isnt tiktok
Could you talk about actual orgasm and ejaculation, next? You've talked sperm production and now erections. But, it would be interesting to learn about things like how spinal cord injuries or spina bifida could affect that aspect.

In my country there is no sex ed and the chapters containing anything about reproduction and puberty are usually skipped by teachers in many schools mainly because how taboo it is. Luckily in my school, my teachers did not skip these lessons even though we had reduced syllabus in covid where these chapters were dropped. But having an understanding of how our genitalia works and how to handle and express our sexuality in a positive and healthy way is important, and I would have never learned about things like: Why erections are natural?, How to handle them?, Why consent is important?, Why are straight men attracted to women and vice versa?, Why are lgbtq attracted to the same gender as their biological gender? and so much more if videos like these didn't exist on the internet. Thank you for making this information available to everyone for free. This is really helpful.
Well said. I was also not taught any sex ed. It's stupid that politicians and schools think that teenagers aren't going to have sex just because they were told to. Actual education is essential for keeping people safe.
How are you meant to learn what to do? Where are you from?
@@enk335I dont think they should tbh. Maybe 16+ and I know they won’t not have it if you just say don’t have it. But with proper education and good communication and a good talk on abstinence that also includes safe sex it would help a lot. We wouldn’t have so many 12 and 13 year olds getting pregnant.
You country is extremely Christian or Muslim religious? That's a typical hallmark.

If us the new generation were actually trying to study most of the time we would probably be better than the previous generation but phones and computers got invented then drugs and things and yeah
For now, he is. Hopefully he's not selling organs and penis tissue in 10 years time.
I really wish channels like this were available 10+ years ago. This would have been so helpful in learning as a student because some professors don’t teach, they just read off slides then expect you to know details on your own for exams.
Anyways. Big respect to this channel always making some of the more “awkward” topics very educational and informative. I appreciate your content!
if u dont understand the concept, why dont u ask questions to better your understanding?
Neon, I know of some people who also didn't get proper answers but, I was very lucky my biology professor was also my English professor and when he asked the girls to go for " extra " home economics class and closed the doors behind them we and I mean all the guys knew what was about to transpired. Oh, I forgot to mention that professor was the best looking man we've ever seen. He would use himself as a model of the male anatomy (yes, really) and what we learned from his class was invaluable. We came to learn that we were all different some will and others won't (measure up to the teacher) 🙂 but, we learned everything we needed to know. Five Doctors out of this classroom and a few lawyers, not bad if this would happen today he would be in jail. But we did learn from him.
that's horible.
Or how about 30 years ago, when parents rented videos to explain things. 😆

TBH social stigma is litrally going down and down throughout my life i have observed. There's more sexual education, theres enough porn on internet that people dont litrally dont make fun of it anymore in my rela life experience. Current generation of below 40 years of age will be responsible for lesser and lesser eradication of social stigma especially regarding HEALTH. PENIS is penis so what? Without it we will seize to exist. Am i wrong?

What's a Montessori
@@neellavgogoi4975 Its for the little ones I guess.
Beautifully explained. Did you say there is a similar proceeds involving the clitoris? ? A video dedicated to the physiological mechanisms of coitus would be so interesting !
Yes, people with a clitoris can get erections as well.
In evolutionary terms, the foetus always starts off as female until testosterone starts to take over then, when the foetus is born and becomes male then the clitoris has in fact become a glans. What women have in evolutionary terms is a vestigial penis. That is why we, as men have a perfect scar that starts on the scrotum and continues afterwards. Why, because that scar would have become the outer labia if we had been born females.
They are homologous to each other so they are similar in this regards.
@Вaлepия Лeбeдeвa Embryos don't start out as female; embryos will become female unless male development is triggered.
Embryos start out with undifferentiated genitals although they resemble female genitals more closely. The genital tubercle is what becomes either the penis or the clitoris later in development, it is much closer to a clitoris and thus doesn't require the same level of development.
Embryos don't start out with vaginas either, the vagina starts out as the urogenital slit, it remains open in females but closes in males which leaves behind a scar on the penis and scrotum. Nevertheless, it is not a fully formed vagina even though it may resemble one.
The penis is just a giant clitoris. So I'm guessing they both work the same way.
You guys are an absolute inspiration!

Thank you so much! As an ex RN, I have never been taught that in depth! I love your videos! They are so informative! 😉
That's funny because as a vet tech student, anatomy and physiology covered all of this except for ED, but we did cover afferent/efferent spinal cord (and obviously infer how damage could affect reproductive function). I believe we go into more depth over all these things because there's such a large variety of subfields we might find ourselves in right after graduation. Fun fact; certain animal species like cattle, sheep, pigs, deer, etc do not experience venodilation into cavernous tissue as a means of erection. Instead of blood the corpus cavernosa of the penis is filled with fibrous (fibroelastic) tissue. The penis is contracted into an S shaped flexure internally via a muscle group called the penis retractor muscles. To get an erection the male must extend the penis via relaxation of those muscles.
