Around the world the age of consent varies, and is as low as 11. Japan is 13 and Germany 14.

Thanks for that website chart on age of consent. By my count, only 10 states set it at 18. Most (27) are at 16 and the rest are 17.
I find it ironic that some of the most liberal states (Cal, NY, Oregon) arnd some states that are the butt of incest jokes like Ark and W. Virginia are at 18.
I think the proper POV is that young girls become women with sexual activity at ages far younger than their parents might like in our society. And we have all known for years that girls sometimes start sexual activity in middle school.
Facts of life in our culture is that rich older men often team up with younger women, sometimes because they project an attractive image of the alpha male.
