Did The Penis Evolve For Her Pleasure?
Losing the spines and bone was an improvement. Prove me wrong.

Have you ever wondered why gorillas have such minuscule penises (3cm/1.25 in.) and large testicles while humans have larger penises (13.12cm/5.16 in.) and small testicles? Even our closest human relatives, chimpanzees and bonobos, have small penises — 8cm or 3.14 in.
Some anthropologists have theorized that our early ancestors adapted larger penises to please the ladies. The larger penises felt better, so more women chose those men. Thus generation after generation, tiny gorilla-sized penises were weeded out through sexual selection.
Unfortunately, anthropologists can’t go back in time and measure our early hominids’ genitals, but you can bet we have some very creative dick pics on cave walls.
The above is a representation of a paleolithic drawing found in Cueva de Los Casares caves in Spain. I am not sure if this is a sex scene or the first example of goat yoga, but either way… that’s a big one. Most anthropologists believe these drawings were shamanistic representations meant to convey fertility rituals.
Obviously, we cannot glean much anatomical information from these fantastical cave drawings. We can only assume that a penis the size of a baseball bat was revered.
But although we don’t know the exact penis size of our prehistoric ancestors, we know that the penis once had spines. Fortunately, we lost that trait. And that might have been the ladies' choice also.
Why did the penis lose its spines?
In a polygamous society, early hominids had much stiffer competition. Women copulated with multiple men in one frisky orgy. Multiple partners meant multiple inseminations. All that sperm competing for one egg… what’s a man to do?
He uses penile spines to remove the sperm of competitors.
Penile spines are tiny bump-like projections made of keratin — the same stuff in your hair and nails. Most primates and mammals still have penile spines, but at some point in our evolutionary story, early hominids lost these spines.
This is going to require a visual. I never thought I would use my medical illustration training to draw studded chimp dicks, but here we are.
As you can see from the above cornucopia of dicks, the human penis is rather dull. No ridges, bumps, or corkscrews. Now I know what you naughty readers are thinking (because I went there too). Penile spines are merely bumps for her pleasure. What’s the problem?
Well, penile spines may have also abraded the vaginal canal, discouraging the young miss from having sex with multiple partners. Nothing like a scrub brush on your lady bits to make a gal monogamous.
Thus, anthropologists have theorized that humans lost their penile spines as we became more monogamous.
But that’s not the only adaptation influenced by mating strategies.
