Thank you edb1984! You're support is just amazing. The argument you brought is really important. Biologically is a girl a woman once she has her menstruation since she can birth children then. (around 13 to 15 I think - I'm not sure) In the history there are a lot a lot of examples where kings would take wifes who are in that age range. I don't support that - I just want to mention it because everything we know is made by society and for example in Germany is a different law than in the US - in Germany children can have sex with other children once they are 14. Adults having sex with under 14 is extremely illegal (that's good) and under 16 is also illegal as far as I know - over 16-18 is a greyzone I think.
And for humans to be attracted to a body of a 16 to 18 year old woman who could be easily 18 or 20+ is similar to a woman who is 24 but looks 16. My girlfriend for example is 28+ but people often think she is under 18. That's not the reason she is my girlfriend of course haha - it's because that I love her.
