in your post on woman's health you said you were a virgin, why would you think this is a std if you are a virgin? have you received oral sex ever?
don't self treat for a vaginal yeast/thrush infection. this sounds nothing like it.
if you continue to have a smelly discharge, follow up properly with your provider.

i really doubt that you can get herpes from the floor. it sounds like you might have thrush. maybe go to the pharmacist and get some thrush treatment.
