Possibly: Exchange of oral fluids has a low transmission rate unless there are punctures, tears, or bleeding in the mouth, lips, or tongue. If you do not know your partner's status then it would be wise to be tested for hiv. Wait 2-3 weeks after contact before getting tested. If the test is negative you may need to return for a second. If your partner does not know her status, she should also be tested.

...: Hiv is transmitted via blood, semen, vaginal fluid, breast milk and any other body fluid containing blood. Unprotected sex is a risk factor. Anal sex is riskier than vaginal sex which is riskier than oral sex. Sharing needles and "works" can transmit hiv. If concerned about acquiring HIV talk to md about testing with HIV pcr viral load which detects virus earlier (window period) than routine test.
