Hurtful sex

So I had sex & I think I cut my vagina a little bit from shaving it stung a little but it wasn’t bleeding nor did I see it I just felt like there was a little something there from the feeling I was getting. I had sex and it hurted a little bit(esp when I wasnt fully aroused) it was just a little uncomfortable feeling at first a little burning when I peed (no I do not have a std or infection) has this happened to anyone after shaving before?
