Okay I'm 17 and weigh 120 I'm about 5'3 so about a month ago I noticed I had some stretch marks on my butt and told my friends about it. As soon as I said that they just started laughing saying I was too skinny and "no offense but you don't have a butt" as if I didn't know already. I'm insecure now bc I feel like I shouldn't have them because apparently I'm too tiny and have no butt.
