At the beginning the characters are introduced entirely based on their favorite sexual position.

Very much sexual dialogue; minimal sex acts shown; no nudity.

A woman asks a couple of girls, approximately age 10, which of them will lose their virginity first. They do not answer and there is no indication they understand.

A woman owns a waxing business for women, for removal of vaginal hair. There is no nudity shown but the act of waxing women is shown a few times.

A woman gives a class on giving oral sex to men; she uses cucumbers to simulate a penis. There is very much dialogue that would be expected in such a class.
