Well the other I masturbated but when I was cumming I felt like it burn. I went to pee and I saw that I was peeing blood and also I felt like I had something obstructing so I pushed and a blod clot came out. Why did it happened?
You may want to explain the whole story to your doctor. Maybe you're just masturbating too aggressively. Blood in the ejaculate can cause great concern to the men who experience it, this condition is called hematospermia. But, it can come from the prostate gland if there's a tear in one of the fragile veins of the prostate. Only an urologist can evaluate your condition. Take care.
