This is what we are exploring in the movie. We tend to exaggerate things. We are a very hypocritical society. Sex is part of nature and denying it doesn't make any sense. It is foolish.
People pretend to deny sex.
Actually, everybody wants it and loves it. They just pretend and that is the sad part. I think it is man's arrogance to deny it. You know sex is just part of nature just like everything else. And your ultimate union happens with nature through it.
