Showed boobs to catfish

So a couple months ago I met this guy off tumblr. we finally skyped for the first time but his side of the camera was really dark and i couldnt see anything. eventually, he asked me to show my boobs, and i did. afterwards he sent me a couple heart emojis but that was it. i havent spoken to him since and he wont reply to my messages. yall, im so scared. ive never  exposed myself to someone ever before and i feel so stupid. Any advice?
