4 Knights Were Honorable, Chivalrous Warriors
Knights were gallant and brave warriors, charging into battle to slay the dragon and rescue the fair maiden.
Knights often had less in common with this:
"We shall die for the glory of our randomly assigned piece of land!"
And more in common with this:

Remember, knights were professional warriors, and when there wasn't a war to fight, they had to find something to do with their war-boners. Most of these guys were relatively young and didn't have Call of Duty to satisfy their violent urges, so they tended to take it out on the local population. Toward the 11th century, many of the local lords started bickering over who would get a slice of the Holy Roman pie that Charlemagne baked, and the knights were at the forefront of these petty wars. These "wars" were less Braveheart-style epic battles and more knights rolling up into villages and slaughtering everybody.
The church tried to curb these conflicts, because frankly, they were nasty and threatened the stability of everything. First they tried to gather up all the knights and shake various body parts of dead saints at them, but when that didn't work, the Pope called the First Crusade and exported all these assholes to the Middle East, where they chivalrously ate babies and massacred the entire population of Jerusalem.
Later attempts were made to get these young 'uns under control, one being the chivalric code that was adopted around the 13th century. Examples like Sir Lancelot and Edward the Black Prince were raised to show knights how to behave in battle and in peace. Knights were encouraged to "defend the weak," but "the weak" was commonly interpreted as noble women and children, not peasants. So noble-on-noble violence may have decreased, but it was still totally cool for knights to kill and rape peasants, since, like those beers you had for breakfast, they didn't really count.
3 Everyone Was a Prude
Casual sex, and even knowledge of how sex works, is a modern invention. During the heavily religious Dark Ages, sex was strictly forbidden outside of marriage, and every single person of consenting age (a term that was very loosely defined back then) led a life that was a never-ending squelch through a pool of their own sexual repression.
You know those really goofy-looking shoes that men wore back then? The extra pointy ones, like something an elf would wear?
We'd still wear those over Heelys.
Well, those points are called poulaines, and apparently they were meant to directly represent the wearer's dong. And in a revelation that will come as absolutely no surprise to anyone even remotely familiar with the intricate relationship between a man and his wang, these points were sometimes so big that dudes couldn't walk up stairs. Good thing they were all wearing those elaborate codpieces to protect their actual dongs when their shoe-dongs tripped them up.
And the sexy didn't stop with their fashion. Prostitution was a big friggin' deal back then. Although technically against the teachings of the church, everyone collectively agreed that if there were no hookers around, men would be out raping, just, everyone, because some of what you've heard about the Middle Ages wasn't a myth. In most medieval cities, prostitution was completely legal yet confined to certain districts and licensed by a town's mayor. The church even got in on this deal and licensed some holy brothels of its very own.
"She'll tickle your schmeckel for only a shekel!"
But let's not leave out the married folk. Since most upper-class marriages were political arrangements and the people getting married didn't necessarily like each other all that much, extramarital affairs were where it was at. And man, did these people get down -- if you've ever watched a show like The Tudors and thought it was all sexed up for a modern audience, you were wrong.
One of the reasons that Eleanor of Aquitaine usurped her husband Henry II was because Henry II apparently had more mistresses than Tiger Woods. Seeing that getting in bed with the king was a good way to get ahead in life, daughters of lower nobility basically became escorts and tried to become the king's favorite mistress, which worked out pretty well for Anne Boleyn when she married Henry VIII and became Queen of England. Worked out pretty well, that is, until she was beheaded for allegedly banging too many people who weren't Henry VIII.
The Bible is very clear that you're only allowed three affairs at a time.
But the whole situation was still bad news for women, right? Because women were basically property back then? Well ...
