I’ve been on prep for a few months now and have been finding it has really helped me feel safer. I am a male and mostly engage in unprotected oral with other men. 

I know the risk is very low even without prep. But I have a specific concern. I had my lower impacted wisdom tooth removed 3 weeks ago. I had planned on avoiding all sexual contact for a month afterwards until the socket healed. 

However, this week (3 weeks out) my extraction socket felt much better so I decided to engage in oral sex with a guy and gave him brief unprotected oral (maybe 1-1.5 mins at most). He did not ejaculate in my mouth, but there may have been pre-seminal fluid. 

On top of that I have had bad allergies this season and my throat has been dry and scratchy (almost a bit sore). 

I keep reading that the only time oral is really a risk is if you have a gaping wound like a tooth extraction, so I have been freaked out a bit by reading that online. 

My socket is no longer bleeding or hurting, but there is still swelling and a hole there, which makes me concerned. 

Does the Truvada prep negate any concern still? Should I feel confident I am safe?
