Addiction

I have sex a lot with multiple guys. I think about sex all the time. I think about past experiences and what I’m going to do next time I have sex. I think about what I’m going to wear and who it’ll be. I got sad and depressed if I don’t have sex in a long time. After having sex the next few days I am in an amazing mood. I have had sex with 11 different guys. I was 14 when I lost my virginity and now I am 17 years old. All my friends think I’m addicted to sex. I don’t think I’m addicted necessarily I just think I enjoy sex- which is a normal human thing. My friends want me to get help. What should I do??
