No, you should absolutely NOT go on PEP. That is for people who have had a high risk for HIV, and you had NO RISK for HIV.
As an adult, the only risks for HIV are:
1) having unprotected, penetrative vaginal or anal sex, or
2) sharing IV drug needles with other IV drug users.
NOTHING else you can think of is a risk. Ignore the cut on your finger - small cuts or scrapes that don't require immediate medical attention are never a risk for HIV transmission. Oral sex is also not a risk.
