why does it hurt when i pee?!

had sex with someone you don't know too well lately?it could also be because of masturbation or you got some kind of infection

Your urethra is too small.

Not to worry though, enlarging it is a snap. It can easily be accomplished with common household items, mainly a golf-tee, a mallet, and a jar of sandy Vaseline.

Good Luck!

I used to get this after masturbating too often. Turns out I was gripping too tight and causing particles of man meat to come out when I peed. After a while of rest, I got back to normal.

You probably have a urinary tract infection. See a doctor right away for antibiotics

it could be those answers, it could be an std...
have you been doing something/one??

You could have a Bladder infection.
