What's the evolutionary advantage of certain animals having small penises?

Average penis size of a human male is around 5.1 inches. Gorillas by comparison only have 1-2.4 inches penis. What's the evolutionary advantage for such a large animal to have such a small penis? Reproduction becomes unnecessarily more difficult.
 
Solution
But why didn't they evolve big dicks like humans did? Humans realized that big penises were necessity to ensure the survival of our species. Our women even have a built in distaste for small penises.
I wonder if this is a result of our social lifestyles and mastery over tools. Our ancestors were less susceptible to the elements since we built shelters and formed small communities. Now that they're not dying so easily to nature the evolutionary pressures change and allow for more fine-tuned adaptations such as a larger penis.
Probably combat advantage. If you're a gorilla, you probably plan to fight a lot against other gorillas, and the last thing you want is for a gorilla to grab and rip off your dick
Yeah, but the main goal of a species is to reproduce, isn't it? Small dick runs very counter to that.
 
It's harder to get punched in the nuts when your peepee is smaller.
Big penis would cover the nuts though.
It's not that gorillas have small dicks, it's that humans have large dicks.

You could also ask why humans didn't evolve huge muscles like gorillas did.
That was never necessary for our survival or to further our race. We were never meant to be the strongest beast, merely the smartest, which we used to hunt and dominate lesser creatures.

That actually sounds pretty convincing. Thanks!
 
No because penis and balls are always the same size. Small dick, small balls. Mid penis, mid balls. Large dick, large balls. Otherwise genitals would look silly.
Fake.

"In that instance, researchers found there wasn't a connection between smaller-than-normal testicle size and testosterone levels or penis size in the men."


Best evidence for such correlation is weak:
"A weak positive correlation was detected between penile length and mean testicular volume"

Pffft, clown world science.

Who are you going to trust more? The mainstream clown world scientists who say women can have dicks and when they turn their girldicks into vagagas and it's bleeding it's the same as having a period or a random shitposter who shitposts and has a cute cat as pfp?
 
It's actually a huge disadvantage when it comes to survival and was bred for luxury, much like a small nose and a beautiful face. Predators can snatch that shit, it can get frostbite, and if you get things like kidneystones it's far worse to pass it through a longer tube as opposed to a shorter one.
 
While human have unusually big dicks, we also have unusually smalls balls. Other manmals are able to breed several dozen times a day, if only for a few seconds at a time. I also don't think big dicks breed more successfully, you're trying to shoot at that uterus, not stab it.
For humans impregnation is the least of our problems, it's bringing up the babys that takes way more time and effort than all other species. I'd argue we're selecting for slowing our reproduction cylce, because historically why were not able to bring even a majority of births to adulthood.
So when you're maintaining a big erection for a long time (the human way), rather than a small erection many short times (monkee) you're probably spending more quality time with your partner, because bitches like it when you look them in the eyes and think of them as people, or whatever. We are also the only animals that sexualize tits, encouraging fucking from the front.
This all leads us to fewer impregnations and more pair-bonding, leading to fewer children but greater investment in co-parenting than other species.

Sperm only travels so far and only lasts so long. Longer dick, smaller distance, more success to have a baby

more success to have a baby
My nigga you only have to hit bullseye once! And you can try as often as you like! You take you wonderdick and impregnate a woman on the first try, and someone else takes fifty tries, you'll each average out one pregnancy a year. And you'll not go around impregnating a hundred other ladies, because you'll want to focus on your babies from that one woman you (hopefully) care about.
If you're thinking of modern fertility rates, they're depressed because we make them so. If two fat people with stressfull jobs decide they're finally having a baby at fourty, their fertility is fucked for reasons that have nothing to do with dick size.

Basically. Humans seem less effected by "natural selection" and have had a higher emphasis placed on sexual selection. It's less a "fine-tuned" adaptation, and more that as human evolution gets guided more by partner selection, aspects that make an appealing reproductive partner get selected for. That's why we have larger dicks, bigger breasts, and are getting taller on average.

Yes, the real question OP should have asked are, "why do humans have such relatively large penises?" Larger sizes carry more risks for injury (often times, depending) and take more energy and nutrients... and in nature, access to sustenance is the main concern.
