Nervous after vigorous fingering 😂

I just recently started seeing this guy and of course after a few weeks things start getting intimate and though we haven't had sex he's fingered me veryyy well but after my vagina around the hole is a bit itchy. Not burning, not even awfully itchy just feels a bit different. I don't think an std can be transferred by fingers 😂 as well as I know he is clean. Is this normal?
