Snapchat Disaster

I have had the worst beginning to my new year. I recently made a sexual snapchat video for my man which I've done for literally like 5 years and I never had any accidents. Tell me why I dropped my phone then it posted to my story and my 21 year old cousin saw it. I'm mortified and feel so ashamed of myself I lliterally feel like a pedophile and I exposed him to shit he should have never even saw. I also feel so violated like even though it was my own fault I still like I was taken advantage. I know it sounds crazy and I take accountability Im just struggling with the emotional consequences at this point. Has anyone been through this before? Should I talk to my cousin about it and apologize?
