HI,
You must understand the way
HIV is transmitted. For a HIV patient, HIV may be detected in various body fluid. That does mean all those fluids are not the transmitting agents. Only specific fluids (blood, semen, vaginal secretions, and breast milk) from an HIV-infected person can transmit HIV. These specific fluids must come in contact with a
mucous membrane or damaged tissue or be directly injected into the blood-stream (from a needle or syringe) for transmission to possibly occur.
For you the condom was intact, You have only swollen head of penis after sex, the possibility through that route is less. The thing is the cut
injury in the finger - was there before you finger fucked her or the cut injury after that. If the cut injury was after you are safe. If it was before it is recommended HIV testing after a potential exposure at 6 weeks, 3 months, and 6 months after exposure.
Even though your partner is not a known case of HIV, it is better to initiate a course post exposure prophylaxis (PEP). The timing of PEP has been proven to be more effective the sooner it is started; preferably less than 6 hours after the exposure but no more than 72 hours
Consult a venereologist
