Oy vey, no. We're talking about all of human history. Or we could even just limit it to 19th century, if you want. For women, sex wasn't divided into clear-cut rape and freely-consenting sex. Reality was: get hitched to whoever will have you, even if he's the town drunkard, or join the nunnery. Sometimes without the latter option being offered at all. Or, you could run away and become a prostitute, which I hope you'll agree isn't exactly a freely-chosen option in such a situation. Options #1 and #3 more often than not led to sexual encounters and pregnancies that they would not have chosen otherwise.
And no, the average 1890s women did not get "a sex ed class or two."

Some girls in the U.S. now don't even get that. Try having zero knowledge of sexuality and then being brutally violated by your semi-arranged husband on your wedding night. And then bearing his kids for the next 20 years without any say in the matter.
