My mom keeps sending pics of me to guys

My stepdad’s nephew likes me & my mom keeps sending him off guard pictures of me. I was eating & noticed she pointed her phone’s camera at me. This isn’t the first time so i asked wtf she was doing, got up & she immediately clicked the send button. Originally, she was sending them to a guy I was talking to. I told her to stop & she said she sent it to “Kevin” which is my stepdad’s nephew cause apparently he “asked for one.” I was furious at this point & stormed to my room, didn’t even finish eating. This makes me super uncomfortable cause wtf! I feel my privacy violated & she doesn’t even care cause she sees nothing wrong with it. I don’t even like him! I’m 17 btw
