Hi About A Month Ago I Shaved My Face And

Hi
About a month ago I shaved my face and then put my shaver away and 2 days ago I shaved my pubes and testicles with the same razor I was wondering if I would get and diseases or herpies because I have kissed a girl and I'm not sure if she has herpies or any diseases, and I have never had sex and because of the shaving I have gotten many pimples and red dots where my pubes were please let me know soon I'm worried what's happened
