Hello there, having an increased sexual desire at certain point of time isn't abnormal but when it leads to over indulgence in self abuse then it may be of much concern. I suggest you to go out of the place, focus on your hobbies rather than your sexual desires, art and music are good ways to get yourself into hobbies if you don't have any. Don't be alone, move out and have fun with your friends or colleagues. Avoid sexual thoughts and don't indulge in visual satisfaction. Always keep one thing in mind anything in excess can harm, similarly over masturbation can also lead to sexual problem in your future life. Hope this helps. If you've any further query feel free to ask questions.
