It depends on the time and place, and it's also hard to tell apart from law since there wasn't Twitter back then for people to air their opinions. One thing you have to consider is that we see teenagers as being a specific age group while for most of history they were immature adults. Generally if a girl had menstruated then she was a woman and only the usual rape or adultery laws applied. Most of the time it was up to the dad, though after Europe became Christian we began developing laws that'd later define statutory rape.
>ancient Rome
Raping a young virgin was a capital offence, though that was up to the girl's father. A prostitute had no protection from rape under the law regardless of age.
>China
Got statutory rape laws around 1200AD, making it a crime to penetrate someone younger than 10. It was punished with exile or death if injury was caused and later it'd bedeath regardless.
>Europe
Generally made 12 the youngest someone could legally go after the Renaissance, though England did it first around the same time as China. The government being involved with people's sex lives was a weird idea to them, it was up to the church and families.
>America
There wasn't any real age of consent as long as the parents were cool with it. It might have been odd to have large age gaps but not illegal.
>Islamic world
They're weird. Everyone knows they prefer girls 9 years old, but what they don't tell you is that they like boys even more. During and after the reign of their prophet boys as young as possible were considered the ideal lovers. There's a far too much gay poetry in Arabic about little boys and it was considered necessary for them to imbibe semen to grow into men. In Libya they even had matchmakers to pair young boys with elderly men.
tl;dr it wasn't taboo like today, the general rule was if she's old enough to get pregnant she was old enough to get married. Parental consent was the age of consent.
