There is a chest hair next to a man's nipple, about four centimeters. Will this kind of hair tie naturally?

No, it will only get denser and denser. The landlord can rest assured that men have long chest hair only because they secrete more androgen, which has no effect on themselves. Follow-up: I found a knot in his chest hair today. I wonder if he has a woman outside, and when he is with a woman outside, women tie the knot while playing. Answer: Khan. I'm not sure about this, but it seems that no man can tie chest hair. Follow-up: it's definitely not him, and it's definitely not a natural knot. According to this reasoning, it should be played by young women who like to play. Answer: Yes. So, someone else did it.

Please accept it, thank you!
