Welcome to the forum.
There's nothing wrong with positng both her and on the community forum. You had accurate replies in both your threads on the other forum. HIV is harder to transmit sexually than you seem to think. Here is a thread that explains the scientific basis for that. (Read it all; some of the key information is in the follow-up comments.)

To start, it is statistically very unlikely any of your sex partners have had HIV, assuming they aren't gay, injection drug users, or immigrants from HIV-endemic areas like tropical Africa. To your specific questions:
1) No HIV infections have ever been known to be transmitted by fingering or other hand-genital contact. Cuts or minor injuries of the hands or genitals might theoretically increase the risk, but still no cases are known -- so you can safely assume no risk, even if one of your partners actually ahs HIV.
2) I suppose this is possible if there is deep penetration.
3) There probably is substantial protection starting about a month after the second dose of vaccine. Of course you should still have the third dose as scheduled.
4) I can't speculate on the cause of bleeding. You should see the doctor or clinic that managed your abnormal pap smear, LEEP, etc.
Having had cervical HPV, dysplasia, and LEEP have absolutely no bearing on your risk for HIV. You really should not be at all worried. Of course all sexually active persons outside mutually monogamous relationships should have HIV testing from time to time, like every 1-3 years. On that basis, consider HIV testing if it hasn't been done recently. But not because of your recent fingering episodes or your HPV/dysplasia history. Based on your sexual lifestyle, you can expect a negative result for sure.
I hope this helps. Best wishes-- HHH, MD
