than there is a risk there does not need to be fluids exchanged if you were in side her without a condom you have a risk.... and need to be tested..... transmittion from viginal fluids from unprotected sex
If you had unprotected sex, there were fluids being exchanged. Vaginal fluid and pre-ejaculate fluid are present even in small amounts during unprotected sex. HIV is transmitted from vaginally secreted fluids that contain the virus.
You should have sex with condoms and use water-based lubricant to prevent condom tearing.
You should get tested for HIV 6-8 weeks after the exposure and 3 months after. A three-month result is conclusive according to CDC guidelines.
