Hello, I Was Having Sex With My Girlfriend (doggy Style)

Hello, i was having sex with my girlfriend (doggy style) and my penus came out and pushed up against her, i felt something warm and thought it was semen but to my surprise it was blood coming out of my urethra. i ran to the shower and started cold water, there was a lot of blood coming out, like urine stream. after a little while i compressed my penis and the blood stopped and i put ice on it and it seems to be ok now with a slight bit of pain, no discoloration yet.
that is it
