Suffering from extreme urge of masturbation and being horny. This is taking away 3-4hrs of my day and I can't study. Pls don't make fun.

Too much desire for physical urges is not letting me study. I have to get up from my library desk, come back to my room to do the drill. It takes almost 2hrs now, and time gets wasted. If I don't do it, my mind will be fixated on the thoughts. At the end of the day I'm just getting anxious, and still there is horniness in me. I'm in a conflicted state. This is really coming up as a big challenge for me. What do I do now ?
