Hi. On January 30 I met a guy at a bar and ended up engaging in oral sex. There was no rimming, no fingering, no penetration. There was only a bit of kissing and I have him fellatio without ejaculation. Three days later I developed a strep throat for which I got prescribed amoxicillin. Since yesterday though I also developed painful defecating. May it be related to any std? Am I at risk of experiencing anal symptoms after oral sex? Thanks I’m advance for your answers.
