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.
