I have read all your concerns and nothing you have mentioned was risk for HIV.
The virus is transmitted through unprotected anal and vaginal intercourse,
you were protected with a condom. Body fluids are not infectious once exposed to air so your other concerns were not risks either. You have NOT had risk.
If these were your only worries it is safe for you to move on.
To avoid infection,
You need to be using condoms for all anal and vaginal intercourse until you are in a trusting monogamous relationship and both have been tested for all STIs and HIV.
Everyone who is sexually active should have an annual exam and test for all STIs and HIV ,and always after unprotected intercourse. Always using condoms will give you peace of mind your tests will return with a negative result.
