In this video, people are knitting their pubic hair and tying it together and circling around.

My parents' job is making pixilation to hide genital parts of pornographic videos. Therefore I was surrounded by a lot of pornography since I was a child, without proper sexual education. I wanted to make a video of sex, not to only excite our body.  The appearance of knitting one's or another's pubic hair is similar to animal grooming.
