Hi, my girlfriend just went in for a STD test today, and upon vaginal inspection she was told that her cervix looked irritated and possibly torn. The worker told her that there was no bacteria present in her vagina, but they gave her antibiotics in case of Chlamydia, and told her it was possible that she had HPV. She has had occasional pinching pains in her abdomen.
We had fairly rough sex about three weeks ago (she is very small and I am well-endowed), and afterwards it hurt her to sit down. My question is: is it possible that this sex could have caused this irritation/tearing in her cervix, or am I positively looking at an STD here?
