Blood in mouth while perfoming oral sex

[greeko]

Im a gay man , rather cautious when it comes to gay sex practises and always do safe sex . Yesterday night i was perfoming oral sex to another partner when all of the sudden we noticed quitte a lot of blood on his penis . Eventually we realized it was my blood although i didn't have any wounds or chest infection or something like that . I don't know if i have developed carries without realizing it . Maybe it had to do with me using mouthwash an hour before in order for my breath to smell a bit better ( stupid i know , but thats what i did ) . What i would like to know are the dangers for me . Im hiv neg , always use condoms and used prep per occasion on top of that . I had taken two tabs one day before and one tab yesterday and i continued it today naturally . Im vaccinated against hep B . What should i be afraid of ? would there be a big risk for hiv infection ? what other stds should i worry about ?
the guy did not ejaculate in my mouth nor did i see much precum

I only read the first sentence of your post because there is no HIV issue. HIV is instantly inactivated in saliva. Also inactivated in air. Double zero risk.
No one in 40 year history got it from oral and you will not be different. Doesn't matter if there are cuts, burns, rashes, dryness etc in the mouth.
There is an std forum for std questions.
