Oral sex after anal sex

So last night I had anal sex then performed oral sex without him cleaning himself. At the time I hadn’t really thought much of it cuz I was pretty wasted. For the most part we didn’t have too much anal sex cuz that shit hurt so we just had oral sex. I’ve been wondering if I can get some sort of infection from this, just a sore throat or some serious disease. I would like to know what you guys think
