Sure it does , for a few particular reasons. One, sex with such a young person would’ve been indeed seen as immoral, even in those times, because we are talking very early teens here. While not necessarily considered children (as we see it today) it was still too early, plus for many, before they reached puberty, and then there’s that whole thing about sex for conception purposes.
Another , is that a lot of people get married so much later nowadays. Late 20’s, 30’s , even 40’s. That’s a very long time to go without sex . You can of course disagree, but we have to be realistic here.
Then, and this is another biggie, there is no real NEED for marriage in the same terms. A woman can get to 30 without being considered an “old maid”, be shunned by society, be considered defective. Women can own property , make and keep their own money etc. They aren’t just an extra burden/mouth to feed /something to get rid of or use for political alliances/financial gains, so much so, the groom deserved payment in return.They don’t need the protection of marriage against being kidnapped, defiled, having then to marry the guy and so on.
My grandfather had to marry my grandmother in a day (they were courting) because they had word a bloke from another village was coming that night to kidnap my (16 yo) grandmother. That would’ve been it. Even if nothing had happened, the fact that she “spent “ the night with him would’ve been enough for her to have to marry him instead.
It’s all pretty fucked up really when you think about it , and it’s less about morality and more about the wants of men and everything that follows.
