he sends me a pic of his penis after i stopped talking to him? was he trying to get back at me?

I met this guy through facebook, never have we met in person. I thought he was a creep and obsessive and would try to be controlling but I was always nice to him anyways though bc I am never mean to people. He would always manipulate me when we would text or talk, make me feel bad...he knew that I was a very nice, and a sweet person. So I guess he saw me as someone he could control I guess. He wanted a relationship with me so badly and told me how I was so beautiful and sweet. He would never stop texting me and get mad if I wouldn't respond I was always too nice to him and he would always make me feel bad so I would always tell him what he wanted to hear bc I was afraid of his actions if I missed him off. I should of kicked him to the curb from the beginning. I finally had the courage and told him that we weren't gonna be anything he got mad and kept blowing my phone up. Then 2 weeks later after not hearing from him he sent me a pic of his penis, I changed my number and blocked him.
