My boyfriend likes to pinch my chest. Why?

Beauty is in the eye of the beholder. My girlfriend always asks me why I always like to touch her chest, because my brain tells me that it makes me feel most comfortable to put my hand on my chest. I have read a scientist's research report, which seems to say that men's hands are the most water-deficient parts of their bodies, while women's breasts are the most water-deficient parts. So men like to touch me. I don't know if it is. But my answer is: because I want to touch it, it is very comfortable, feels good, soft and elastic. I think girls have to admit that you get excited easily when your boyfriend touches your chest. There is no denying that the Internet is straightforward. We don't know anyone. It doesn't matter, but it doesn't matter if you don't admit it If your boyfriend touches your chest, your body will tell you that you feel good. The physical characteristics of women are: the chest is obviously bigger than usual, and some parts of your body will run water. I don't know why I have to touch my chest. Do you like it? I just asked my girlfriend, and one of my female colleagues said that I was horny and my girlfriend would definitely be bullied to death, so I called her on the spot and asked her this question. She will answer me: what do you say? Being bullied by a boyfriend is also a kind of enjoyment. If her boyfriend doesn't bully her, she will still feel unattractive and her boyfriend doesn't like her.
