RISK OF VAGINAL SEX WITH CONDOM
It's hard to say what your risk is -- usually your genitalia would have to have had contact with either her vaginal fluids or blood. If you didn't notice any rectal bleeding on her part and you used a condom from beginning to end, your risk is probably quick low. However, if you are concerned, it would be prudent to get an HIV test three months after the sexual experience just to be sure.
