About 3 months ago I deeply french kissed a woman and possibly briefly touched my mouth to her vaginal area which was covered by underwear. It was so brief I can't remember if that contact oral/vaginal contact happened or not. Anyway, for about 10 days afterward I had a severe sore throat that went away. Now I'm in a relationship and about 2 months after this my female partner developed a severe sore throat that has lasted 2 weeks. Discharge of tonsils and flu-like symptoms are present. Could any of this be due to an STD?
