feeling scared and helpless

At about 4:30 this morning I woke up to my boyfriend touching me downstairs followed by a flash and a click of a camera. It took me a while to catch on to what was going on, I was stuck still and shaking in place. All up he took about 30 photos of me down there and through this I asked him what he was doing and he pretended to be asleep. This morning I woke up before him and saw the photos in his camera roll and he had multiple snapchats from people we used to go to school with, I'm worried he's sent these photos to people because I saw a Snapchat and it was someone asking if he got some ass. I'm not sure what I should do, could someone help me please?
