I always think about sexual things. At first, I thought it was just those natural sex thoughts that come to one's mind now and then but, as time went on, it got worse. I think about sex all the time. I don't know why, I just do. I masterbate all the time. It has become so bad that I refuse to even leave my room. I hardly talk to my family in fear that they'll find out about my problem so I just conceal myself in my room. Honestly, I don't understand what's wrong with me. Do I have a mental disorder or something? If someone has some advice, I'd appreciate it. Thank you
