It could be irritation caused by aggressive penatration, an infection, or STD... The best way to find out is to be seen by your doctor.
Did you bleed at all? If not it's most likely not a tear. I know it's a possibility to have that sensation if you have a latex allergy. If you somehow got a small cut that could be why it hurts to urinate and stuff. That area usually heals pretty fast so if it's still a problem in a few days, you should get it checked out. Could be something to do with an oncoming yeast infection or UTI.
