That's some powerful sex.
I think that's a lot of sex. The desire for sex leads to relationship, relationship leads to commitment, commitment to children. Or sex leads to children, whatever. No matter what, one's life is different. Every act of sex has the potential to be life-changing, to be the turning point of all that comes after. And, more likely than not, no matter how wild the sex, how unreserved or abandoned, in the end it is taming, stifling, controlling. Thus is the paradox and magic of sex. And I think it is really well described in this film.
