Just sore, or something else?

Patient: I have regular sexual contact with a person of the same gender (I am female), and notice that often, the day after contact, my vagina and the area around it will feel irritated and sore. Also, when I urinate, the urine feels warm, and can burn every now and again. I wasn’t sure if it was just a simple yeast infection, or maybe it was just because my vagina is getting frequent attention. Do you know what’s up with me?

Symptoms: Light vaginal itching and dryness, urine feels hot when it comes out
