Feeling insecure

Every time I go to the gym my bf asks me if I’m working on my booty. And idk if I’m overthinking but I feel like he wishes my ass looked like all the asses you see on social media today. There is so much pressure to have a big ass and lift heavy weights. And I finally snapped today. Like NO. I did not work on my booty again today. You can’t just work on one muscle everyday. He’s asked me everyday of the week.
