I don't feel turned on any more, Could it be because of a massive headache I had from potassium?

I have been masturbating since I was 9 years old after my "brother" introduced me to it, I didn't have sperm yet.. And the first time it took a lot to get orgasm... I achieved it and got orgasm being 9 years old.. There was no sperm of course.. And the orgasm wasn't that big as far as I remember... Now I'm 21 years old and I've been masturbating a lot, now I quit because I do not feel turned on anymore the way I used to... It couldn't be cause of masturbating a lot or getting too old... Before I stopped feeling turned on my ears were ringing really hard and buzzing.. Could it be cause of tooth nerve infection that I had the dentist infected it even more and I struggled for almost 2 months in pain until dentist cleaned it and removed the nerve... Could it be cause of a massive headache I had from potassium? I've been poisoned like 6 times since I've been 18 years old.. Could it be cause of that I've been stabbed with a needle in stomach? Or that 3 months ago I masturbated and tried not to have orgasm - to get longer pleasure out of it.. Masturbated to the limit but stopped at the points where I get orgasm.. And did that 3 times till I stopped for 2 minutes then I masturbated to the end and finally had orgasm, and came.. I could feel the sperm filling up or something in my I'll just call it "Sperm bubble" after those 3 times and waiting 2 minutes.. I could feel the warm sperm filling up.. I've felt it twice.. Also my penis is pumped with blood all the time now even in cold it's still big without erection.. Why is it pumped with blood all the time? Have I malfunctioned my organism? Now I'm coming like a girl after getting hard, but I don't feel turned on
