Bitting cuticle(worn skin) fingering,Wet Frotting. PEP?

Hello Doctor, I made the mistake of visiting a CSW and payed for frotting (from over the underwear), while my underwear was very wet and my penis had some sensitive skin inside due to masturbation.

While frotting I was fingering the CSW with the finger which I was biting some time back and had a sensitive skin. (No bleeding but sensitive skin was visible). Now I am regretting like hell over this bad habit of biting fingers. I am scared to total stress. I am around 32 hours over the incident. I want to ask if I should immediately rush for PEP? Thank you very much doctor for answering this.
