Hi I Had Protected Oral Sex. I Was The Receiver.

Hi I had protected oral sex. I was the receiver. The condom was intact and I don't see it was burst while I have removed. I haven't seen any blood on condom also. I am not sure if salvia came to down to the pubic area, I cleaned myself after 2 hours. I had shaved my pubic area before 5 days of the encounter.
I have questions:
1. The risk for HIV? considering salvia may be present in the pubic area?
2. is it true salvia doesn't transmit HIV even small blood present?
3. Once outside HIV can't survive?
2. Risk for other STDs?
if any test when to do?
