Suggest Remedies For Swollen, Itchy, Sore And Irritated Vagina

Hi, my boyfriend fingered me a few hours after eating chicken flavoured chips (specifically JJ s snacks). He didn t wash his hands and stupidly I thought nothing of it. Now my vagina is slightly swollen, extremely itchy and sore. It is highly irritated and is giving off a bad odour and a white-yellow discharge making my undies smell like urine. I can t get to the doctor right now, would you please recommend some home remedies for relief as well as a diagnosis. If it helps, he also ejaculated on the outside of my vagina where some saliva, semen and lube also rubbed off on my skin down there.
