You wouldn't get anything from the clitoris slapping, but you could get gonorrhea, chlamydia or NGU from the oral sex.
You could also have a totally unrelated UTI.
You might also be dehydrated or have something else totally unrelated.
The only way you'll know is to see your doctor for testing.
One more thing, I never inserted my oenis, but I did slap her clit with it a couple of times. Thought that should be noted.
