2 weeks ago I had sex for the first time and it hurt a bit at the time but the pain went away the next day but now the inside of my vagina has started to uncomfortable,a bit sore when i touch it and a bit of a burning sensation at times. We were both virgins and i am on the pill-he didn't use a condom but once he was inside I had to tell him to remove it-to sore and he didnt ejaculate. Could I have a bladder infection?
