Ok, I am a college student at a major university. Recently, i was dating someone there and his roommate (who i didn't know was there) busted in and took a picture of us during sex. I told him to get out as soon as i knew he came in, but he still snapped a picture of me. Later, i asked him to delete it and he said he did, and that there was nothing to worry about. Eventually i stopped dating that guy and now he is threatening me to broadcast those pictures to everyone at my school. He apparently is upset about me leaving him, but i am more upset that my naked body could be broadcasted over the internet without my consent. is there any legal action that i could take to prevent this?
