Has any serious scientist or academic types ever bothered to investigate why some men have larger penises?
There are two aspects of evolution: natural selection and sexual selection. Natural selection is aspects of your environment (including the society) that make you more likely to arrive at a mating opportunity, e.g. disease resistance, strength, strong bones. Sexual selection are traits that make you more likely to be selected by females once a possible mating opportunity arises.
The distribution of traits you find in humans are which were selected most in natural and sexual selection. So in terms of penises it's not a surprise that micro-penis (around 2.5" or less is) is present in only about 1 in 200 males. Particularly in times when there was no stigma with going nude, that wasn't going to whet girl's leaf or make it easy to get her pregnant.
So it's no surprise that the average penis size more or less mirrors the average depth of a vagina (+ a bit of fat/angle). The average penis is about 5.25" and the average vagina about 4.5" when aroused. Then you look at other species and you'll find the same thing. Same across continents. Asian men are about 4.25" on average and then women and their vaginas are smaller. West African men are about 6.25" on average and the women are bigger with deep Penis fits in vagina.
The way the distribution of a trait in society shifts is if it becomes more useful for reproducing over multiple generations. Given that penis size fits quite nicely with vagina size it's apparent that it is a deep evolutionary trait that has moved slowly with other traits. The evidence in terms of the distribution of penis size tells you that penis that are overly small or overly large compared to a vagina are deselected. It's not an evolutionary factor beyond that.
There was no reason in history for larger penises to be selected naturally or sexually. Trying to glug on a mega-cock is a modern luxury for fat schlubs from New York, it seems. And by the looks of it, it doesn't look like they're going to be flooding the gene pool any time soon.

Being in the changing room at the swimming pool in Russia for two months (where guys walk around rude with abandon) has convinced me that the scientific literature on penis size is correct, though you'd be hard pushed to believe it in contrast to self-reporting, which seems to be about 1.5-2" over actual size.
From the reliable and uniform scientific literature that uses the BPEL measure (pushing a ruler into any fat next to the penis) a 7" penis is possessed by around 1 in 12 guys. For 8 inches you are looking at about 1 in 300 and 9 you are probably looking at 1 in 10,000 if not more.
It's very apparent that women also lie or are clueless on penis size. In such videos/literature as above, these women who say they've had a decent number of men have tried a few 8s, a 9 or a 10. Bullshit. You've had sex with 20 guys and somehow slept with a throng from the vag-crushing 0.01%.
There's a good site (can't find it) that shows a girl holding up various sizes of length and girth cylinders next to her vagina. 9 inches is utterly ridiculous, which is why it's so rare. Even 7 is going to give a girl a deep stir. For most women, a legitimate 7 is going to cause pain.
I suspect most of the people in that video are using the butt-pressed measuring method.
