The most open concept of sex in the world
As far as sexual concepts are concerned, the United States is undoubtedly the most open place in the world. On the university campus, men and women living together and passionately kissing are daily scenes. What's more, many schools hold streaking festivals. At that time, countless students were running naked on campus, forming a unique landscape.
