Now think this through. The highest density of nasty bacteria in the entire body is in the rectum. That is the downwar part of the bowel that leads to the anus. A penis in there is surrounded by enterobacteria - the primary cause of urethral infection in both men and women. Any movement at all is pushing some into the entrance to his urethra.
The first indicator of urethral infection in men is burning while urinating. This may get worse and it may seem better but that infection, once it takes hold, will remain and move upward to his prostate. In severe cases the infection can move to the bladder and even up to the kidneys.
This is an STD only in hte sense that he contracted the infection through some form of sex play. If he stuck it up there uncovered, he was asking for it. Most of the time I see a male patient fearing an STD, it is actually "non-specific urethritis." That comes from normal migration of the bacteria and it comes from anal sex. It would not be likely that it would be noticeable the next morning. It takes the bacteria a while to reproduce to the level where it is causing pain.
Tell him to go to a doctor; we see urethritis every day. Then tell him to take a hike. He is levelling pretty serious allegations against you simply because of his (and your) ignorance.
