I also have an anal fissure and noticed some blood the following day. I did not bottom or have any anal contact with anyone. I was mainly looking for a place to crash for the night. Any exposure here?
You never had an exposure. Oral sex is NOT a risk of HIV transmission.
there is no way you can get hiv from falling on the floor. the hiv virus dies in the presence of air. although there is a tiny theoretical risk from receiving hiv from oral sex, there are no reported cases of it. there is also no hiv risk by giving hand jobs.
