I have had unprotected oral sex a few times from a provider, it has been 4 months since the last time. I have went down a rabbit hole on STIs, even though I don’t have symptoms at all. I keep reading that syphilis is on the rise, gonorrhea and chlamydia could be likely but also that even if you don’t have symptoms you could be asymptomatic. AI also does not help as it seems they are getting information directly from the CDC. 

I don’t have any symptoms, never seen a sore, no discharge, no rash. Am I at risk here? Is testing needed? I do have a partner and they don’t have any symptoms either.
