Is it normal that i use sex as a temporary escape from life's problems?

I've been having sex every since I was 14 years old. I know thats young but I digress. Four months after getting placed in foster care I began having sex with a neighbor. That didnt last, of course, so every since then I have been in and out of relationships. I know where I lose respect from guys; when I have sex with them too soon. The thing is, I dont want to wait. Sex takes me to a new world. Rather I feel loved or used afterwards, I love the feeling. For the past year (it started exactly 12 months from the current month) I have been watching porn when my sex mate is not available. The first time I had a clitoral stimulated orgasm I wanted it again and again. At that point it had gotten so bad that I rubbed the top layer of skin off of my clitoris. Then I had to purchase a toy. Everytime something goes wrong I want to fuck or lay back with a good porno clip.

I am an 18 year old female. Is this normal? Am I addicted to porn?
