feeling horny easily with tiredness and sleepiness

hello, I'm a 20 years old male with a masturbation record since 12 to 14 years old since I started averaging about once a day or once every two days , I have had no real health issue during my life I'm always healthy and strong I rarely get sick never needed a doctor.
my problem is that I recently (like a week ago) I felt like I could cum without touching it I got worried and started experimenting as anyone would to cope down the worries, but when I let it go it just goes high on that feeling but doesn't cum, since then whenever I masturbate it's so easy to cum like if I go fast it would cum I can't control it, this is not the problem but the problem is that this made me get triggered very easily and want to fap more even walking and seeing a girl fapping comes on my mind with a boner start I could hardly control it, as well as thinking of anything sexy like a porn scene makes me get started and want to fap easily, I also noticed a decrease in my urination tension I can't urinate hard and long like before also feeling that my bladder isn't completely empty after urinating and wanting to urinate after minutes. Going with all this a feeling of tiredness and sleepiness all day it gets less intense at night since I have a sleep disorder I sleep at around 3am to 5am. I searched the internet as anyone would do and it as usual led me to prostate cancer and all this crap it matched like 50% of the symptoms but I don't think it is since prostate cancer at my age is very rare.
so can anyone who had this experience or know anything about it help me ? because it's so annoying at times and distracting especially that I am an engineering student and need to be focused well on my study.
thanks

 

thanks, I can do that I've already done 10 days since it started I can try do more and my diet is healthy I don't eat anything I know is crappy but need to work on the sleeping. Hopefully this goes away.
