Does anyone else get extremely horny when trying to focus?

I'm trying to write a paper, it's due in 4 days. I still have another 14 pages to write, but whenever I sit down to work, I am almost immediately distracted by intense horniness, both mentally and physically. I've tried masturbating, I've tried abstaining, I've tried inserting toys into myself to give myself a low level of stimulation, I've tried using numbing gel, I've tried going on walks or taking a small break. I've even tried slapping my genitals! Nothing seems to work, and I'm scared that I might fail this class if I can't manage to submit this paper. If I try to ignore it, the arousal climbs until my face is burning hot, I'm ruining my boxers, and I've even had tears start to well up in my eyes. Those are just the physical symptoms, mentally I am plagued by brain fog to the point where I can get dizzy.

I've spoken to my doctor about this, since the dizziness made me worry a bit, and he told me that some young men react to boredom with strong sexual urges, and that I just need to try to calm down and focus.

Any ideas? Tips? Has anyone else ever experienced this before?
