Getting to these specific exposures, I would rate them all as zero risk for HIV
, or very close to it. Oral sex is extremely low risk, even with HIV
infected partners, is very low risk, and kissing and hand-genital contact and fingering have never been known to transmit HIV. From a medical or risk standpoint, you didn't need testing. However, the negative test results you report are reliable in regard to the event 4 and 7 weeks later.
