This happened a few years ago, and obligatory apologies for mobile. 

My girlfriend at the time (ex now) was obsessed with popping my pimples. Sometimes it was nice if I asked her to, but very frustrating most of the time, as she would do it whenever she wanted and it would hurt like hell, but she would just continue despite me visibly getting upset with her. 

This particular incident happened 3 years ago in  my college dorm room. I was laying on my stomach on the bed and she started popping pimples on my back. This went on for at least a half hour, and hurt very badly. In her defense, I did not explicitly tell her to stop, but we had been dating well over a year and she knew me well enough to tell from my mannerisms I was very annoyed. 

Finally I got up and went to the bathroom and noticed in my mirror that there were welts all over my back from where she had been pinching. I came back into the room and got pretty mad at her, at which point she got mad at me for being mad and saying it was not that big of a deal. There was no long term damage and the welts went away but it hurt like hell and I felt like I was justified in being mad. 

AITA?
