Vagina Anxiety

So I was masturbating earlier and (this is about to get very detailed I'm sorry) I asked my boyfriend to tell me what to do while we were texting and he said to out two fingers in and go as hard and fast as possible so when I was doing that the inside and the outside of my vagina kinda felt like they were burning. And I had cleaned my hands previously. So I'm not sure if it was from shaving two days ago or not? Please help this is giving my anxiety.
