If he pees on my vagina during sex will I get an infection?

No. Body fluids such as semen, vaginal secretions, and blood are capable of transmitting a variety of infections/stds. However, urine cannot transmit infection by contact mainly because the urine itself tends to "dilute" the microorganisms leading to less virulence/infectability.

Infection/UTI. Yes it surely suggest you have a vaginal infection with urinary tract infection, whether it is std can only be detected by exam and culture of the discharge and urine. I will suggest you get it checked by your family doctor or gynecologist.
